0.2.12

## New Features
- Added support for custom models with the simulstreaming backend via the `--model_dir` parameter.  
- Added the ability to set a custom alignment head when using custom models, using `--custom-alignment-heads`. If not specified, the system defaults to using the last half of the decoder layers for time alignment.  
- Unified HTML, CSS, and JavaScript between the Chrome extension and web interface:  
  - The extension interface now includes the latest functionality.  
  - The web interface features improved responsive design for narrow viewports.  
- Added the `--forwarded-allow-ips` parameter to enable WebSocket functionality behind a reverse proxy.  
- Prepared backend for the new API version, doc [here](https://github.com/QuentinFuxa/WhisperLiveKit/blob/main/docs/API.md)
