Add RAG embedding and AI chat feature
Implement end-to-end RAG pipeline: AST-aware code chunking, LiteLLM embedding generation, MongoDB vector storage with brute-force cosine similarity fallback for self-hosted instances, and a chat API with RAG-augmented responses. Add dedicated /chat/:repo_id dashboard page with embedding build controls, message history, and source reference cards. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
