feat: Implement CCW Coordinator for interactive command orchestration

- Add action files for session management, command selection, building, execution, and completion.
- Introduce orchestrator logic to drive state transitions and action selection.
- Create state schema to define session state structure.
- Develop command registry and validation tools for command metadata extraction and chain validation.
- Establish skill configuration and specifications for command library and validation rules.
- Implement tools for command registry and chain validation with CLI support.
