- isUserBoundShortcutEvent skips toggleSessionSidebar (it has its own gate) and an
entry re-captured onto its own default, so ^L still reaches the CLI.
- Re-enabling a shortcut and Reset run the duplicate check and refuse when the
chord was taken meanwhile; Ctrl/Shift+Enter and Ctrl/Cmd+V are reserved with
Alt+1-9, and the Alt-digit check no longer excludes Cmd.
- Alt+[ / Alt+] keep their Alt/Option+[ labels via displayBindings.
- Behavioural tests (vm harness) replace the source-string test.
- Docs: wiki Rebinding / Why-chords-behave-oddly, architecture-invariants note.
- Small: _shortcutActions indentation, stale Alt-block comment, typeof check
instead of Object.hasOwn, full-width parentheses in zh-CN.
