The key matcher only consulted event.code when a binding explicitly
opted in via codeFallback. macOS rewrites event.key whenever Option
is held (Option+T -> "†", Option+[ -> "“", Option+Shift+W -> "„",
etc.), so the comparison against combo.key always failed and every
Alt-bound letter / bracket shortcut silently stopped firing on Mac:
Cmd+Alt+T (cycle theme), Alt+Shift+[/], Alt+[/], Alt+Shift+W.
Fall back to event.code when combo.alt is set. Keep the existing
key-first behaviour for non-Alt bindings so Dvorak users still get
logical-character matching (Cmd+V on physical Period keeps pasting
instead of triggering Cmd+. for sidebar toggle).
