feat(ui): add quick shortcuts panel with add/edit/delete support
Adds a compact shortcuts row inside the composer panel for one-click
instruction queuing, with full lifecycle management stored in localStorage.
Features
--------
- Six built-in defaults (Stop, Summarize, Explain error, Undo, Continue, etc.)
- Click any chip → instantly POSTs to /api/instructions, no typing required
- Cyan border pulse on fire; green glow flash on success
- Edit mode (toggle button in header):
- Per-chip edit (✏) button → replaces chip with inline input, Enter to save
- Per-chip delete (✕) button → removes with vanish animation
- '+ Add' chip → inline form appended below rail
- All changes persisted to localStorage key 'local-mcp-shortcuts'
- Accessible: button elements, aria-labels, keyboard support (Enter/Escape)
