feat(sqlite): enhance SQLite initialization and IPC handlers

Browse Source 
This commit significantly improves SQLite database management and IPC communication
in the TimeSafari Electron app. Key changes include:

- Add new IPC handlers for database lifecycle management:
  - sqlite-open: Open database connections
  - sqlite-close: Close database connections
  - sqlite-is-db-open: Check database connection status
  - get-path: Retrieve database path
  - get-base-path: Get base directory path

- Enhance SQLite initialization with:
  - Improved error handling and recovery mechanisms
  - Detailed logging for all database operations
  - State verification and tracking
  - Proper cleanup of IPC handlers
  - Transaction state management

- Security improvements:
  - Validate all IPC channels
  - Implement proper file permissions (0o755)
  - Add connection state verification
  - Secure error handling and logging

- Performance optimizations:
  - Implement WAL journal mode
  - Configure optimal PRAGMA settings
  - Add connection pooling support
  - Implement retry logic with exponential backoff

Technical details:
- Add SQLiteError class for detailed error tracking
- Implement handler registration tracking
- Add comprehensive logging with operation tagging
- Update preload script with new valid channels
- Add type definitions for all SQLite operations

Testing:
- All handlers include proper error handling
- State verification before operations
- Recovery mechanisms for failed operations
- Logging for debugging and monitoring
