Jeff Emmett	fee72573ba	feat: system clock heartbeat + ephemeral clock delivery (TASK-47) ... Server-side SystemClock broadcasts tick/5min/hourly/daily events via WebSocket to all connected clients. Events are ephemeral (not persisted in CRDT). Client-side fallback clock activates when server connection is lost. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-11 16:20:04 -07:00
Jeff Emmett	efb5810b31	feat: canvas event broadcasting pub/sub system (TASK-43) ... Add CanvasEventBus with emit/subscribe/unsubscribe for cross-shape communication.
