Update tests for Linux compatibility and resolve merge conflicts

✅ **Merge Conflicts Resolved**
- Merged latest changes from main branch
- Resolved conflicts in docs/spec.md by keeping comprehensive specification
- Added PEEKABOO_CLI_TIMEOUT environment variable documentation

🧪 **Test Suite Updates for Linux Compatibility**
- Added platform-specific test skipping for Swift-dependent tests
- Created tests/setup.ts for global test configuration
- Updated vitest.config.ts with platform detection
- Modified integration tests to skip on non-macOS platforms:
  - tests/integration/peekaboo-cli-integration.test.ts
  - tests/integration/image-tool.test.ts
  - tests/integration/analyze-tool.test.ts

📦 **New Test Scripts**
- `npm run test:unit` - Run only unit tests (any platform)
- `npm run test:typescript` - Run TypeScript tests, skip Swift (Linux-friendly)
- `npm run test:typescript:watch` - Watch mode for TypeScript-only tests

🌍 **Platform Support**
- **macOS**: All tests run (unit + integration + Swift)
- **Linux/CI**: Only TypeScript tests run (Swift tests auto-skipped)
- **Environment Variables**:
  - `SKIP_SWIFT_TESTS=true` - Force skip Swift tests
  - `CI=true` - Auto-skip Swift tests in CI

📚 **Documentation Updates**
- Added comprehensive testing section to README.md
- Documented platform-specific test behavior
- Added environment variable documentation for test control

This allows the TypeScript parts of Peekaboo to be tested on Linux while maintaining full test coverage on macOS.

+## Testing
+
+Peekaboo includes comprehensive test suites for both TypeScript and Swift components:
+
+### TypeScript Tests
+
+- **Unit Tests**: Test individual functions and modules in isolation
+- **Integration Tests**: Test tool handlers with mocked Swift CLI
+- **Platform-Specific Tests**: Some integration tests require macOS and Swift binary
+
+```bash
+# Run all tests (requires macOS and Swift binary for integration tests)
+npm test
+
+# Run only unit tests (works on any platform)
+npm run test:unit
+
+# Run TypeScript-only tests (skips Swift-dependent tests, works on Linux)
+npm run test:typescript
+
+# Watch mode for TypeScript-only tests
+npm run test:typescript:watch
+
+# Run with coverage
+npm run test:coverage
+```
+
+### Swift Tests
+
+```bash
+# Run Swift CLI tests (macOS only)
+npm run test:swift
+
+# Run full integration tests (TypeScript + Swift)
+npm run test:integration
+```
+
+### Platform Support
+
+- **macOS**: All tests run (unit, integration, Swift)
+- **Linux/CI**: Only TypeScript tests run (Swift-dependent tests are automatically skipped)
+- **Environment Variables**:
+  - `SKIP_SWIFT_TESTS=true`: Force skip Swift-dependent tests
+  - `CI=true`: Automatically skips Swift-dependent tests
+
