This commit establishes a comprehensive native menu system for the Tauri application, bringing it to parity with the Electron implementation and enabling full keyboard shortcut support.
## Key Features Added
**Native Menu System:**
- Complete menu bar with File, Edit, View, and Window menus
- Platform-specific adaptations (macOS app menu, Windows/Linux quit behavior)
- Full menu event handling system with proper window management
**Keyboard Accelerators:**
- CmdOrCtrl+N for New Instance creation
- Standard Edit menu shortcuts (Undo, Redo, Cut, Copy, Paste, Select All)
- View menu shortcuts (Reload, Force Reload, Toggle DevTools, Fullscreen)
- Built-in zoom hotkeys enabled via zoomHotkeysEnabled
**Enhanced Capabilities:**
- Added core:menu:default permission for menu management
- Added core:webview:allow-set-webview-zoom for zoom functionality
- Proper event communication between Tauri backend and frontend
**Frontend Integration:**
- Tauri event listener for menu:newInstance events
- Proper cleanup and error handling for event subscriptions

## Technical Changes
**Backend (Rust):**
- Replaced empty menu stub with full SubmenuBuilder implementation
- Added comprehensive menu event handling with window operations
- Implemented MenuItem::with_id for accelerator support
- Added platform-specific menu construction logic
**Frontend (TypeScript):**

- Runtime environment detection for conditional Tauri behavior
**Configuration:**
