Add a Python-based code review agent powered by LangChain that
integrates with OpenFang via the A2A (Agent-to-Agent) protocol.
- agent.py: Core review logic with structured Chinese SYSTEM_PROMPT
covering 6 dimensions (correctness, security, performance,
maintainability, testing, style) and 4 severity levels
- server.py: FastAPI server exposing A2A-compatible endpoints
(/.well-known/agent.json and /a2a JSON-RPC)
- workflow.json: OpenFang workflow definition for the review pipeline
- config.example.toml: Example A2A config for ~/.openfang/config.toml
- Supports OpenAI, DeepSeek, and Ollama backends
