Test User f3c9e828e2 refactor: integrate secure file system operations across services
This commit replaces direct file system operations with a secure file system adapter to enhance security by enforcing path validation. The changes include:

- Replaced `fs` imports with `secureFs` in various services and utilities.
- Updated file operations in `agent-service`, `auto-mode-service`, `feature-loader`, and `settings-service` to use the secure file system methods.
- Ensured that all file I/O operations are validated against the ALLOWED_ROOT_DIRECTORY.

This refactor aims to prevent unauthorized file access and improve overall security posture.

Tests: All unit tests passing.
