Subject: [PATCH] Add fullscreen mode with F11 and ESC keyboard shortcuts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements basic fullscreen toggle functionality for immersive video playback.

Fullscreen Features:
- F11 key toggles fullscreen on/off
- ESC key exits fullscreen mode
- Window.SetFullScreen() for native fullscreen
- isFullscreen state tracking in appState

Keyboard Shortcuts:
- F11: Toggle fullscreen (globally available)
- ESC: Exit fullscreen (only when in fullscreen mode)
- Shortcuts work from any screen in the app

Implementation:
- Added isFullscreen bool to appState
- Created toggleFullscreen() method
- Global keyboard handler in runGUI()
- SetOnTypedKey handles F11 and ESC

Usage:
1. Load a video in VT_Player
2. Press F11 to enter fullscreen
3. Press F11 or ESC to exit fullscreen

Next Steps:
- Add fullscreen button to player controls
- Auto-hide controls after 3 seconds in fullscreen
- Show controls on mouse movement in fullscreen
- Double-click video to toggle fullscreen
