Add debug development server mode for hot reload (#316)

* feat: add debug development server mode for hot reload

Added a debug mode that allows running the web server in development mode with hot reload instead of using the built-in compiled server. This significantly speeds up web development by eliminating the need to rebuild the Mac app for web changes.

Changes:
- Added DevServerManager to handle validation and configuration of dev server paths
- Modified BunServer to support running `pnpm run dev` when dev mode is enabled
- Added Development Server section to Debug Settings with path validation
- Validates that pnpm is installed and dev script exists in package.json
- Passes all server arguments (port, bind, auth) to the dev server
- Automatic server restart when toggling dev mode

To use:
1. Enable Debug Mode in Advanced Settings
2. Go to Debug Settings tab
3. Toggle "Use development server"
4. Select your VibeTunnel web project folder
5. Server restarts automatically with hot reload enabled

* fix: improve pnpm detection for non-standard installations

The previous implementation failed to detect pnpm when installed via npm global or in user directories like ~/Library/pnpm. This fix:

- Checks common installation paths including ~/Library/pnpm
- Uses proper PATH environment when checking via shell
- Finds and uses the actual pnpm executable path
- Supports pnpm installed via npm, homebrew, or standalone

- Shows "VibeTunnel Debug" when debug mode is enabled
- Appends "Dev Server" when hot reload dev server is active
- Updates both the menu header and accessibility title
- Dynamically updates when toggling dev server mode

* fix: add pnpm directory to PATH for dev server scripts

The dev.js script calls 'pnpm exec' internally which fails when pnpm
is not in the PATH. This fix adds the pnpm binary directory to the
PATH environment variable so that child processes can find pnpm.

This fixes the server restart loop caused by the dev script failing
to execute pnpm commands.

* fix: set working directory for dev server to resolve pnpm path issues

The dev server was failing with 'pnpm: command not found' because:
1. The shell script wasn't changing to the project directory
2. pnpm couldn't find package.json in the current directory

Fixed by adding 'cd' command to change to the project directory before running pnpm.

* feat: improve dev server lifecycle and logging

- Added clear logging to distinguish dev server from production server
- Show '🔧 DEVELOPMENT MODE ACTIVE' banner when dev server starts
- Added proper process cleanup to kill all child processes on shutdown
- Added graceful shutdown with fallback to force kill if needed
- Show clear error messages when dev server crashes
- Log server type (dev/production) in crash messages
- Ensure all pnpm child processes are terminated with pkill -P

This makes it much clearer when running in dev mode and ensures
clean shutdown without orphaned processes.

* fix: resolve Mac build warnings and errors

- Fixed 'no calls to throwing functions' warnings in DevServerManager
- Removed duplicate pnpmDir variable declaration
- Fixed OSLog string interpolation type errors
- Changed for-if loops to for-where clauses per linter
- Split complex string concatenation to avoid compiler timeout

Build now succeeds without errors.

* refactor: centralize UserDefaults management with AppConstants helpers

- Added comprehensive UserDefaults key constants to AppConstants
- Created type-safe helper methods for bool, string, and int values
- Added configuration structs (DevServerConfig, AuthConfig, etc.)
- Refactored all UserDefaults usage across Mac app to use new helpers
- Standardized @AppStorage usage with centralized constants
- Added convenience methods for development status and preferences
- Updated README.md to document Mac app development server mode

+- Express server serves updated files immediately
+- Visit `http://localhost:4020` and refresh to see changes

+For true hot module replacement without manual refresh, see our [Vite migration plan](docs/vite-plan.md) which would provide:
+- Instant updates without page refresh
+- Preserved application state during development
+- Sub-second feedback loops
+- Modern development tooling
+
+#### Mac App Development Server Mode
+
+The VibeTunnel Mac app includes a special development server mode that integrates with the web development workflow:
+
+**Setup:**
+1. Open VibeTunnel Settings → Debug tab (enable Debug Mode first in General settings)
+2. Enable "Use Development Server"
+3. Set the path to your `web/` directory
+4. Restart the VibeTunnel server
+
+**How it works:**
+- Instead of using the bundled production server, the Mac app runs `pnpm run dev` in your web directory
+- Provides hot reload and automatic rebuilding during development
+- Maintains all Mac app functionality (session management, logging, etc.)
+- Shows "Dev Server" in the menu bar and status indicators
+
+**Benefits:**
+- No need to manually rebuild after code changes
+- Automatic esbuild watch mode for instant compilation
+- Full integration with Mac app features
+- Same terminal session management as production
+
+**Alternative: Standalone Development**
+
+If you prefer working outside the Mac app:
 
 1. Build the web project: `cd web && pnpm run build`
 2. In VibeTunnel settings, set Dashboard Access to "Network"
 3. Access from external device: `http://[your-mac-ip]:4020`
 
-Note: This requires rebuilding after each change, so the dev server method above is preferred for rapid iteration.

+# Vite Migration Plan for VibeTunnel
+
+## Overview
+
+This document outlines a comprehensive plan to migrate VibeTunnel's build system from esbuild to Vite. The migration would provide hot module replacement (HMR), faster development cycles, and modern tooling while maintaining full compatibility with the Mac app's embedded server architecture.
+
+## Why Consider Vite?
+
+### Current State (esbuild)
+- Fast builds but manual browser refresh required
+- Watch mode rebuilds automatically but no HMR
+- Custom build scripts and configuration
+- Good performance but not optimal development experience
+
+### Vite Benefits
+- **Lightning Fast HMR**: Sub-50ms updates with instant feedback
+- **Native ESM**: Modern ES modules, better tree shaking
+- **Rich Plugin Ecosystem**: Monaco, PWA, TypeScript support built-in
+- **Superior Developer Experience**: Better error messages, dev tools
+- **Industry Standard**: Active development, future-proof
+- **Framework Agnostic**: Works well with LitElement
+
+## Architecture Understanding
+
+### Development vs Production
+
+**Key Insight: Vite has two completely separate modes**
+
+#### Development Mode
+```
+Vite Dev Server (port 4021) ← Developer browsers
+    ↓ (proxies API calls)
+Express Server (port 4020) ← Mac app spawns this
+```
+
+#### Production Mode  
+```
+Vite Build → Static Files → Mac App Bundle → Express Server
+```
+
+**The Mac app never ships with Vite** - only the compiled static assets.
+
+### Current vs Future Architecture
+
+#### Current (esbuild):
+```
+Development:
+  esbuild watch → public/bundle/client-bundle.js
+  Express server (port 4020) serves public/ + API
+  Browser: http://localhost:4020
+
+Production:
+  esbuild build → static files
+  Mac app embeds static files → serves via Express
+```
+
+#### Future (Vite):
+```
+Development:
+  Vite dev server (port 4021) → native ESM + HMR
+  Express server (port 4020) → API only  
+  Vite proxies /api calls to Express
+  Browser: http://localhost:4021
+
+Production:
+  Vite build → same static files as esbuild
+  Mac app embeds static files → serves via Express (UNCHANGED)
+```
+
+## Technical Implementation Plan
+
+### 1. Dependencies
+
+#### Remove
+```bash
+pnpm remove esbuild
+```
+
+#### Add
+```bash
+pnpm add -D vite @vitejs/plugin-legacy vite-plugin-monaco-editor
+pnpm add -D @vitejs/plugin-typescript vite-plugin-pwa
+pnpm add -D rollup-plugin-copy
+```
+
+### 2. New File Structure
+
+```

+│   └── server/                 # Unchanged: Express server
+```
+
+### 3. Vite Configuration
+
+**Key configuration challenges:**
+
+#### Multiple Entry Points
+Vite expects HTML files as entry points, unlike esbuild's JS entries:
+
+```typescript
+// vite.config.ts
+export default defineConfig({
+  build: {
+    rollupOptions: {
+      input: {
+        app: resolve(__dirname, 'src/client/index.html'),
+        test: resolve(__dirname, 'src/client/test.html'),
+        screencap: resolve(__dirname, 'src/client/screencap.html'),
+      },
+      output: {
+        entryFileNames: (chunkInfo) => {
+          if (chunkInfo.name === 'app') return 'bundle/client-bundle.js';
+          if (chunkInfo.name === 'test') return 'bundle/test.js';
+          if (chunkInfo.name === 'screencap') return 'bundle/screencap.js';
+          return 'bundle/[name].js';
+        }
+      }
+    }
+  }
+});
+```
+
+#### Development Server Proxy
+```typescript
+server: {
+  port: 4021,
+  proxy: {
+    '/api': {
+      target: 'http://localhost:4020',
+      changeOrigin: true
+    },
+    '/buffers': {
+      target: 'ws://localhost:4020',
+      ws: true  // WebSocket proxy for terminal connections
+    }
+  }
+}
+```
+
+#### TypeScript Decorators (LitElement)
+```typescript
+plugins: [
+  {
+    name: 'typescript-decorators',
+    config(config) {
+      config.esbuild = {
+        tsconfigRaw: {
+          compilerOptions: {
+            experimentalDecorators: true,
+            useDefineForClassFields: false
+          }
+        }
+      };
+    }
+  }
+]
+```
+
+### 4. HTML Entry Points
+
+**Current**: JavaScript files are entry points  
+**Future**: HTML files import JavaScript modules
+
+```html
+<!-- src/client/index.html -->
+<!DOCTYPE html>
+<html lang="en">
+<head>
+  <meta charset="UTF-8">
+  <meta name="viewport" content="width=device-width, initial-scale=1.0">
+  <title>VibeTunnel</title>
+  <link rel="stylesheet" href="./styles.css">
+</head>
+<body>
+  <vibetunnel-app></vibetunnel-app>
+  <script type="module" src="./app-entry.ts"></script>
+</body>
+</html>
+```
+
+### 5. Service Worker Migration
+
+**Challenge**: Current service worker uses IIFE format
+**Solution**: Use vite-plugin-pwa with injectManifest strategy
+
+```typescript
+VitePWA({
+  strategies: 'injectManifest',
+  srcDir: 'src/client',
+  filename: 'sw.ts',
+  outDir: '../../public',
+  injectManifest: {
+    swSrc: 'src/client/sw.ts',
+    swDest: '../../public/sw.js'
+  }
+})
+```
+
+### 6. Monaco Editor Integration
+
+**Current**: Custom esbuild plugin  
+**Future**: vite-plugin-monaco-editor
+
+```typescript
+monacoEditorPlugin({
+  languageWorkers: ['editorWorkerService', 'typescript', 'json', 'css', 'html'],
+  customWorkers: []
+})
+```
+
+### 7. Asset Handling
+
+**Current**: Custom copy-assets.js script  
+**Future**: Vite plugin or built-in asset handling
+
+```typescript
+// Custom plugin to replicate copy-assets.js behavior
+{
+  name: 'copy-assets',
+  buildStart() {
+    // Copy assets from src/client/assets to public
+  }
+}
+```
+
+## Migration Steps
+
+### Phase 1: Setup (Week 1)
+1. Install Vite dependencies alongside esbuild
+2. Create basic `vite.config.ts`
+3. Create HTML entry point templates
+4. Test basic Vite build without removing esbuild
+
+### Phase 2: Entry Points (Week 2)  
+1. Configure multiple entry points in Vite
+2. Ensure output file names match current structure exactly
+3. Test each entry point (app, test, screencap) individually
+4. Verify bundle output structure compatibility
+
+### Phase 3: Service Worker (Week 3)
+1. Configure vite-plugin-pwa for service worker
+2. Test service worker registration and functionality
+3. Verify push notifications and offline capabilities
+4. Ensure IIFE format is maintained
+
+### Phase 4: Monaco Editor (Week 3)
+1. Replace custom Monaco plugin with vite-plugin-monaco-editor
+2. Test Monaco functionality in both development and production
+3. Verify language workers and syntax highlighting
+4. Test file editing capabilities
+
+### Phase 5: Development Server (Week 4)
+1. Configure Vite proxy for Express server APIs
+2. Test hot reloading and asset serving
+3. Ensure WebSocket proxying works for terminal connections
+4. Verify all API endpoints function correctly
+
+### Phase 6: Production Build (Week 5)
+1. Test full production build process
+2. Verify all assets are copied correctly
+3. Test Mac app integration with new build output
+4. Performance testing and bundle analysis
+
+### Phase 7: Final Migration (Week 6)
+1. Update package.json scripts
+2. Remove esbuild dependencies and configurations
+3. Clean up old build scripts (build.js, dev.js, esbuild-config.js)
+4. Update documentation and team workflows
+
+## Critical Compatibility Requirements
+
+### Output Structure Must Match Exactly
+
+**Current Output:**
+```
+public/
+├── bundle/
+│   ├── client-bundle.js
+│   ├── test.js
+│   └── screencap.js
+├── sw.js
+├── styles.css
+└── index.html
+```
+
+**Future Output Must Be Identical** - The Mac app's `BunServer.swift` expects this exact structure.
+
+### Mac App Integration Points
+
+1. **Static File Serving**: Mac app serves `public/` directory via Express
+2. **Entry Points**: Mac app loads specific bundle files by name
+3. **Service Worker**: Registration paths must remain the same
+4. **Asset Paths**: All asset references must use same relative paths
+
+## Risks and Mitigation
+
+### High Risk
+- **Mac App Compatibility**: Build output structure changes could break embedded server
+- **Mitigation**: Extensive testing of Mac app integration, maintain exact file paths
+
+### Medium Risk  
+- **Service Worker Functionality**: PWA features are core to VibeTunnel
+- **Mitigation**: Thorough testing of service worker registration and push notifications
+
+- **WebSocket Proxying**: Terminal connections rely on WebSocket proxy
+- **Mitigation**: Test all WebSocket connections during development
+
+### Low Risk
+- **Development Workflow Changes**: Team adaptation to new commands and ports
+- **Mitigation**: Clear documentation and gradual migration with parallel systems
+
+- **Monaco Editor**: Complex integration that needs careful migration
+- **Mitigation**: Test editor functionality extensively in both modes
+
+## Benefits vs Costs
+
+### Benefits
+- **Developer Experience**: Sub-second feedback loops, instant HMR
+- **Modern Tooling**: Native ESM, better tree shaking, rich plugin ecosystem  
+- **Performance**: Faster builds, better optimization
+- **Future Proofing**: Industry standard with active development
+- **Bundle Analysis**: Built-in analysis and optimization tools
+
+### Costs
+- **3-4 weeks dedicated migration work**
+- **Risk of breaking production during migration**
+- **Team workflow changes and learning curve**
+- **Potential compatibility issues with current Mac app integration**
+
+## Recommended Approach
+
+### Option A: Full Migration
+- Commit to 4-6 week migration timeline
+- High reward but significant risk and effort
+- Best long-term solution
+
+### Option B: Proof of Concept
+- Create parallel Vite setup alongside esbuild
+- Test compatibility without disrupting current workflow
+- Validate assumptions before full commitment
+
+### Option C: Defer Migration
+- Implement simple auto-refresh solution instead
+- Revisit Vite migration as dedicated project later
+- Lower risk, faster developer experience improvement
+
+## Conclusion
+
+Vite migration would significantly improve VibeTunnel's development experience with modern HMR and tooling. However, it requires substantial effort and carries migration risks due to the complex Mac app integration.
+
+The migration is technically feasible but should be considered carefully against current project priorities and available development time.
+
+**Key Decision Point**: Is 4-6 weeks of migration work worth the improved developer experience, or should we implement a simpler auto-refresh solution first?
