admin ec33ac1936 Refactor cockpit to use DockerTmuxController pattern
Based on claude-code-tools TmuxCLIController, this refactor:

- Added DockerTmuxController class for robust tmux session management
- Implements send_keys() with configurable delay_enter
- Implements capture_pane() for output retrieval
- Implements wait_for_prompt() for pattern-based completion detection
- Implements wait_for_idle() for content-hash-based idle detection
- Implements wait_for_shell_prompt() for shell prompt detection

Also includes workflow improvements:
- Pre-task git snapshot before agent execution
- Post-task commit protocol in agent guidelines
