fix: eliminate duplicate WebSocket messages during agent history priming

- Skip dispatching individual agent_stream events when replaying history
  (the snapshot is sent after priming anyway, so individual events were wasted)
- Add WebSocket message logging on client (type, size, id) for debugging
- Change default daemon URL from dev to localhost
- Clean up unused imports in session.ts
