Subject: [PATCH] Fix terminal keyboard event handling to allow browser
 shortcuts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The terminal component was aggressively preventing default on ALL keyboard events, blocking important browser shortcuts like F12 (DevTools), Ctrl+C/Ctrl+V (copy/paste), and Ctrl+F (find).

Updated the keyboard handler to:
- Allow F12 and Ctrl+Shift+I/Cmd+Alt+I for DevTools
- Allow common browser shortcuts like Ctrl+A, Ctrl+F, Ctrl+R, etc.
- Allow Alt+Tab and Cmd+Tab for window switching
- Only preventDefault on keys that are actually handled by the terminal

This preserves terminal functionality while restoring essential browser shortcuts.
