feat: broadcast pilot agent traces via WebSocket for live status on reconnect

Agent trace logs are now stored in-memory (pilotRunStore) and broadcast
through the existing /ws/crm-updates WebSocket channel. When a client
reconnects, it receives a pilot.catchup with all accumulated logs so the
user sees agent progress even after page reload. Three new WS event
types: pilot.trace, pilot.finished, pilot.catchup.
