Add OpenAI-compatible chat completions endpoint with streaming support.
Currently returns mock lorem ipsum responses (Ollama integration pending).
Chat Router (src/chat/router.py):
- POST /v1/chat/completions endpoint
- Streaming and non-streaming support
- SSE format with EventSourceResponse
- 20-second timeout protection
- OpenAI-compatible response format
Chat Schemas (src/chat/schemas.py):
- ChatMessage, ChatCompletionRequest
- ChatCompletionResponse, ChatCompletionChoice
- ChatCompletionChunk for streaming
- Full OpenAI API compatibility
Chat Service (src/chat/service.py):
- create_chat_completion() - non-streaming
- create_chat_completion_stream() - streaming word-by-word
- Mock lorem ipsum responses
- Token usage calculation
Chat Constants (src/chat/constants.py):
- OpenAI API constants for consistency
- Object types, roles, finish reasons
Following Best Practices:
- Business logic in service layer
- Router only handles HTTP concerns
- Async generators for streaming
- Type hints throughout
Model: mistral-nemo:latest
Status: Mock implementation (ready for Ollama integration)
