feat: Enhance CLI tools and settings management

- Added auto-initialization of CSRF token for state-changing requests in cli-manager.js.
- Refactored Claude CLI Tools configuration to separate tools and settings into cli-tools.json and cli-settings.json respectively.
- Introduced new interfaces for Claude CLI Tools and Settings, including support for tags and primary models.
- Implemented loading and saving functions for CLI settings, ensuring backward compatibility with legacy combined config.
- Updated functions to synchronize tags between CLI tools and configuration manager.
- Added error handling and logging for loading and saving configurations.
- Created initial cli-settings.json with default settings.
