feat(feature-list-protection): implement multi-layered protection strategy for feature list

- Removed the `FEATURE_LIST_PROTECTION.md` documentation file as the protection strategy has been fully implemented.
- Updated the `.automaker/feature_list.json` to an empty array to prevent accidental data loss.
- Enhanced the context management and prompt generation to include critical warnings and memory content for agents.
- Added validation, auto-backup, and access control mechanisms to safeguard the feature list from direct modifications.

These changes ensure robust protection against data loss and improve the overall safety of feature management within the application.
