feat(root): implement dynamic todo list refresh and UI enhancements

This change adds a mechanism to refresh the todo list dynamically when the underlying service updates, improving UI responsiveness and user experience. It also updates documentation and removes deprecated files.

- New Features:
  - Added `_refresh_todos` method to rebuild the todo list when `get_todo_service().todos` changes.
  - Introduced `TodoListCapture` class for mouse capture handling of the todo list window.
- Enhancements:
  - Updated README with corrected image paths, installation tips, and manual installation commands.
  - Introduced `start.py` to launch the application or lock mode.
  - Removed deprecated `config.json` and `debug_memory.py`.
- Bug Fixes:
  - Fixed lock screen screenshot path in README.
