feat: Add validation action and orchestrator for CCW Loop

- Implemented the VALIDATE action to run tests, check coverage, and generate reports.
- Created orchestrator for managing CCW Loop execution using Codex subagent pattern.
- Defined state schema for unified loop state management.
- Updated action catalog with new actions and their specifications.
- Enhanced CLI and issue routes to support new features and data structures.
- Improved documentation for Codex subagent design principles and action flow.
