W8: Added Ctrl+, as a standard Settings accelerator alongside the existing
Ctrl+K palette shortcut. The key handler now handles both in one listener
so there's a single window.addEventListener lifecycle.
W9: Command palette now restores focus to the previously focused element when
it closes. prePaletteRef stores document.activeElement at open time;
onClose fires a requestAnimationFrame focus-restore after unmounting the
palette, so the focus returns to the trigger (a sidebar nav button, the
URL input, etc.) rather than leaving focus stranded at the document body.
typecheck + 242 tests green.
