Add platform adapters and tests for CLIProxyAPI, OneHub, Sub2API, and title hint detection

- Implemented `CliProxyApiAdapter` with detection logic for CLIProxyAPI.
- Added tests for `CliProxyApiAdapter` to verify detection and response handling.
- Created `OneHubAdapter` with methods for fetching models and user groups.
- Added tests for `OneHubAdapter` to ensure correct fallback and response parsing.
- Developed `Sub2ApiAdapter` with detection and user info fetching capabilities.
- Added comprehensive tests for `Sub2ApiAdapter` covering various scenarios.
- Introduced `TitleHintPlatform` type and detection logic based on HTML title.
- Implemented tests for title hint detection to identify platforms from URLs.
