feat: enhance model and tools integration with auto-selection functionality

- Added a new `toolIds` field to the `Model` class to support tool identification.
- Implemented `modelToolsAutoSelectionProvider` to automatically apply model-specific tools when the selected model changes.
- Enhanced the logic to filter and set valid tool IDs based on available tools, improving user experience by ensuring relevant tools are automatically selected.
- Updated the default model auto-selection provider to initialize the new tools auto-selection feature, ensuring seamless integration within the app's lifecycle.
