LM Studio Integration:

- Added LM Studio provider with OpenAI-compatible API support
- Dynamic model discovery via /v1/models endpoint
- Support for both chat and embeddings models
- Docker-compatible networking configuration
- Thinking Model Panel:

Added collapsible UI panel for model's chain of thought
-Parses responses with tags to separate reasoning
-Maintains backward compatibility with regular responses
-Styled consistently with app theme for light/dark modes
-Preserves all existing message functionality (sources, markdown, etc.)

These improvements enhance the app's compatibility with local LLMs and provide better visibility into model reasoning processes while maintaining existing functionality.
