* feat: add mihomo_api crate as a workspace member
Added a new mihomo_api crate to handle interactions with the Mihomo API. This modular approach provides a dedicated interface for fetching and managing proxy data from Mihomo servers. The implementation includes functionality to refresh and retrieve both proxies and provider proxies with proper error handling and timeouts. Added this crate as a workspace member and included it as a dependency in the main project.
* Refactors Mihomo API integration
Simplifies proxy fetching by removing the MihomoManager structure.
Updates the get_proxies and get_providers_proxies functions to directly use the mihomo_api module.
Removes unused Mihomo API related files and modules for cleaner codebase.
Enhances overall maintainability and performance.
• Introduce new API caller implementations for Mihomo in model and module layers.
• Add configuration and API integration files under /src-tauri/src/config/api and /src-tauri/src/model/api.
• Implement a singleton MihomoAPICaller with async API call support and integration tests.
• Create a new MihomoManager module to refresh and fetch proxies from the API.
• Update Cargo.lock and Cargo.toml with additional dependencies (async-trait, env_logger, mockito, tempfile, etc.) related to the Mihomo API support.
