- Rename file to lowercase: CCW-COORDINATOR.md → ccw-coordinator.md
- Replace polling waitForTaskCompletion with stop-action blocking model
- CLI commands execute in background with immediate stop (no polling)
- Hook callbacks (handleCliCompletion) trigger continuation to next command
- Add task_id and completed_at fields to execution_results
- Maintain state checkpoint after each command launch
- Add status flow documentation (running → waiting → completed)
- Include CLI invocation example with hook configuration
- Separate concerns: orchestrator launches, hooks handle callbacks
- Support serial execution: one command at a time with break after launch
