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

+ * Autonomous improvement system for sub-agent coordination based on ACE framework.

+ * 
+ * Key Innovation: Delta updates (incremental changes) prevent context collapse and

+ * 
+ * Performance: ~10.6% improvement on agent tasks, 86.9% lower adaptation latency
