Refactor workflow session commands to utilize ccw CLI for session management

- Updated session completion process to use `ccw session` commands for listing, reading, and updating session statuses.
- Enhanced session listing command to provide metadata and statistics using `ccw session list` and `ccw session stats`.
- Streamlined session resume functionality with `ccw session` commands for checking status and updating session state.
- Improved session creation process by replacing manual directory and metadata handling with `ccw session init`.
- Introduced `session_manager` tool for simplified session operations, including listing, updating, and archiving sessions.
- Updated conflict resolution tools to generate structured output in `conflict-resolution.json` instead of markdown files.
- Enhanced TDD and UI design tools to utilize `ccw cli exec` for executing analysis commands, improving integration with the workflow.
