Running langgraph dev inside a uv-managed project

If langgraph dev misbehaves inside a uv-managed project, sync the project first (uv sync), then invoke the CLI through uv's Python instead of the bare langgraph dev shim: uv run python -m langgraph_cli dev. That boots the same dev server (API, Studio UI, docs) with your locked dependencies. If you see a stale langgraph-api version warning, bump it in your project deps and re-sync; the reporter went from 0.4.28 to 0.5.x this way.
