perf: fix memory leaks — strip task outputs from SSE broadcasts, use light state everywhere

- TaskTracker.getTaskTreeLight(): strips large `output` strings from tasks
  in SSE broadcasts (was serializing 5-10MB every 500ms with many subagents)
- session:created broadcasts now use toLightDetailedState() (consistent with
  session:updated which already did)
- GET /api/sessions/:id returns light state (no 2-3MB terminal+text buffers)
- Ralph wizard polls /terminal?tail=2048 instead of full session endpoint
