* Add Linux implementation of VibeTunnel
This commit introduces a complete Linux port of VibeTunnel, providing feature parity with the macOS version. The implementation includes:
- Full Go-based server with identical REST API and WebSocket endpoints
- Terminal session management using PTY (pseudo-terminal) handling
- Asciinema recording format for session playback
- Compatible CLI interface matching the macOS `vt` command
- Support for all VibeTunnel features: password protection, network modes, ngrok integration
- Comprehensive build system with Makefile supporting various installation methods
- Systemd service integration for running as a system daemon
The Linux version maintains 100% compatibility with the existing web UI and can be used as a drop-in replacement for the macOS app on Linux systems.

* Add comprehensive ngrok integration to Linux VibeTunnel
Implements full ngrok tunnel support for the Go/Linux version to match
the macOS Swift implementation, enabling secure public access to local
VibeTunnel instances.
- **ngrok Service**: Complete lifecycle management with status tracking
- **HTTP API**: RESTful endpoints matching macOS version
- **CLI Support**: Command-line ngrok flags and integration
- **Auto-forwarding**: Built-in HTTP request forwarding to local server
- `POST /api/ngrok/start` - Start tunnel with auth token
- `POST /api/ngrok/stop` - Stop active tunnel
- `GET /api/ngrok/status` - Get current tunnel status
- Uses `golang.ngrok.com/ngrok` SDK for native Go integration
- Thread-safe service with mutex protection
- Comprehensive error handling and logging
- Real-time status updates (disconnected/connecting/connected/error)
- Proper context cancellation for graceful shutdown
```bash
vibetunnel --serve --ngrok --ngrok-token "your_token"
vibetunnel --serve --port 4030 --ngrok --ngrok-token "your_token"
```
- Added golang.ngrok.com/ngrok v1.13.0
- Updated web packages (security fixes for puppeteer)
Maintains full API compatibility with macOS VibeTunnel for seamless
cross-platform operation and consistent web frontend integration.

* Fix SSE streaming performance with byte-based approach
Addresses @badlogic's review feedback to prevent performance issues
with line-based file reading in processNewContent().
## Changes Made
### Performance Fix
- **Byte-based seeking**: Replace line counting with file position tracking
- **Efficient reads**: Only read new content since last position using file.Seek()
- **Memory optimization**: Avoid reading entire file on each update
- **Incomplete line handling**: Properly handle partial lines at file end
### Technical Details
- Changed lastLineCount *int → seenBytes *int64
- Use file.Seek(seenBytes, 0) to jump to last read position
- Read only new content with currentSize - seenBytes
- Handle incomplete lines by adjusting seek position
- Maintains same functionality with better performance
### Benefits
- **Scalability**: No longer reads entire file for each update
- **Performance**: O(new_content) instead of O(total_content)
- **Memory**: Constant memory usage regardless of file size
- **Reliability**: Handles concurrent writes and partial lines correctly
This prevents the SSE streaming from exploding in our faces as @badlogic
warned, especially for long-running sessions with large output files.

* Optimize streaming performance to reduce 1+ second delays
Implements multiple optimizations to address user-reported 1+ second delay
between typing and stream rendering:
## PTY Reading Optimizations
- **Reduced sleep times**: 100ms → 1ms for EOF checks
- **Faster polling**: 10ms → 1ms for zero-byte reads
- **FIFO optimization**: 1s → 100ms for stdin EOF polling
## UTF-8 Buffering Improvements
- **Timeout-based flushing**: 5ms timer for incomplete UTF-8 sequences
- **Real-time streaming**: Don't wait for complete sequences in interactive mode
- **Smart buffering**: Balance correctness with responsiveness
## File I/O Optimizations
- **Immediate sync**: Call file.Sync() after each write for instant fsnotify
- **Reduced SSE timeout**: 1s → 100ms for session alive checks
- **Better responsiveness**: Ensure file changes trigger immediately
## Technical Changes
- Added StreamWriter.scheduleFlush() with 5ms timeout
- Enhanced writeEvent() with conditional file syncing
- Optimized PTY read/write loop timing
- Improved SSE streaming frequency
These changes target the main bottlenecks identified in the
PTY → file → fsnotify → SSE → browser pipeline.

* Fix critical performance issues causing resource leaks and CPU burns
Performance optimizations based on code review feedback:
1. **Fix SSE goroutine leaks**:
- Added client disconnect detection to SSE streams
- Propagate write errors to detect when clients close connections
- Prevents memory leaks from abandoned streaming goroutines
2. **Fix PTY busy-loop CPU burn**:
- Increased sleep from 1ms to 10ms in idle scenarios
- Reduces CPU wake-ups from 1000/s to 100/s (10x improvement)
- Significantly reduces CPU usage when PTY is idle
3. **Multi-stream disconnect detection**:
- Added error checking to multi-stream write operations
- Prevents goroutine leaks in multi-session streaming
These fixes address the "thing of the things" - performance\!

* Standardize session creation API response format to match Rust server
Changes:
- Updated Go server session creation response to include success/message/error fields
- Now returns: {"success": true, "message": "Session created successfully", "error": null, "sessionId": "..."}
- Maintains backward compatibility with existing sessionId field
- Go server already supported both input formats (cmdline/command, cwd/workingDir)
This achieves protocol compatibility between Go and Rust implementations.
