Cmd/Ctrl+T now opens the focused pane's launcher, while explicit target shortcuts bypass the menu. Dispatcher ownership is scoped to the app tree so retained workspaces cannot intercept commands.
Replace all hardcoded shortcut key rendering with useShortcutKeys() so
rebound shortcuts always display correctly. Add Cmd+O (new worktree),
Cmd+Shift+Backspace (archive worktree) with proper active-project
scoping. Show shortcut hints in tooltips and dropdown menus. Fix tooltip
alignment to center, bump dropdown menu surface level, simplify
TerminalPane to single-terminal, and add special key display symbols.
