v0.7.4
Fixed
- Shortcut editor rewritten for cross-browser support — Firefox uses inline recording editor (commands.update); Chrome redirects to chrome://extensions/shortcuts since the API is unavailable
- Shortcut key detection — uses e.code (physical key) instead of e.key to fix Alt/Option on Mac producing special characters
- Alt keyup menu activation — suppressed on Windows only when an exact configured Alt shortcut is pressed
- Duplicate shortcut prevention — shows error when assigning a shortcut already used by another command
- Suspend timer — now resets when leaving a tab, not when entering it; staying on a tab no longer causes immediate suspension on switch
- Favicon caching — favicons are cached as base64 (Firefox) or via Chrome's _favicon API before suspending, so they display reliably on the suspended page
- Browser-specific default hotkeys — Chrome: Ctrl+Shift+S / Ctrl+Shift+Z; Firefox: Ctrl+Shift+U / Ctrl+Shift+Y; Mac: Alt+Shift+S / Alt+Shift+A

Changed
- Suspended page titlebar: timer moved to left on Windows/Linux, window controls on right; title centered on all platforms
- Window control buttons restyled for Windows and Linux
