feat(T23): LangGraph retry loop for trending curator - #9
Merged
Conversation
Replaces the one-shot trendingCuratorAgent call with a small LangGraph StateGraph: on invalid/unparseable output, retries once with the validation error fed back into the prompt, then gives up and alerts via Telegram instead of silently returning an empty repo list. Also adds LangSmith tracing (env-var only, no code changes needed), a node:test + tsx unit test suite for the retry graph, and updates the README to match current setup (OpenRouter LLM provider, testing, observability).
