Add DeepSeek Support to CodeBuddy

Changes

• Implemented DeepseekWebViewProvider to support DeepSeek API integration
• Added DeepSeekLLM class to handle model requests and function calls
• Updated application constants to support DeepSeek configurations
• Added DeepSeek to available models list in extension.ts
• Created unit tests for DeepSeek provider

Testing

The implementation has been tested by:

• Verifying the provider can be initialized with API key and model
• Confirming chat history is properly maintained
• Testing message sending and receiving functionality
• Validating API calls to DeepSeek endpoints

Configuration

Users will need to add their DeepSeek API key in settings:

• deepseek.apiKey: API key for DeepSeek
• deepseek.model: The DeepSeek model to use (e.g., "deepseek-coder")

Fixes #138
