/**
 * The ⌘B sidebar bug interlude (owner, 2026-09-25): ⌘B did nothing because
 * the sidebar listened on the pre-convention "lh:toggle-sidebar" while the
 * dispatcher sent "lh:kbd-toggle-sidebar". The fix is structural — both
 * sides compose the event name through the ONE helper — and these pins
 * hold the chain together: the registry maps the keypress to the action,
 * the helper spells the event, and the UI dispatcher imports the same
 * helper (not its own copy).
