- Updated CLI tool components to accept initial status as a prop, improving state management for tool statuses.

- Added functionality to fetch and set statuses for various CLI tools (Claude, Codex, Droid, OpenClaw, Antigravity) on component mount.
- Enhanced error handling and logging in the OAuth provider test utilities and DNS management functions.
- Improved the MITM server to handle multiple target hosts and provide clearer error messages regarding port usage.
