Patch Update Notice

Hello everyone! This update mainly improves custom APIs, voice generation, and the overall Steam experience.

## Custom APIs

- Fixed an issue that prevented some custom LLM APIs from working because of browser cross-origin restrictions.
- Added and improved presets for DeepSeek, Google Gemini, Qwen, and other models.
- Improved compatibility with Qwen reasoning models.
- Improved connection tests and retry handling for custom models to reduce occasional loading failures.

## Voice

- StepFun voice now supports both the Standard API and Step Plan API.
- StepFun users can select a concurrency level that matches their account tier, helping reduce rate-limit errors.
- Fixed an issue where a Workshop character's reference voice could be previewed but failed to generate speech during a story.
- Improved support for reading and uploading reference audio in formats such as MP3 and WebM.
- Improved voice generation and voice matching across different languages.
- Added a voice indicator to the save list, making saves with generated voice easier to identify.

## Steam Experience

- The mute button in the top-right corner of a story now affects only the current story and no longer changes the global sound setting.
- Added an “Exit Game” button to the main menu.
- Simplified Steam error messages and removed technical error IDs that were difficult for players to understand.
- Fixed and improved the display and use of some Live2D and Workshop characters.
