Implements pkg/keybinding with three-layer pattern: IPC Bus -> Service -> Platform. Service maintains in-memory registry, ErrAlreadyRegistered on duplicates. QueryList reads from service registry, not platform.GetAll(). ActionTriggered broadcast on shortcut trigger via platform callback. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
