Protobuf Stubs

After changing src/sangam/proto/sangam.proto, regenerate Python stubs and typings with the repo-owned script.

Regenerate

uv run python scripts/generate_protobuf.py

The script:

• runs grpc_tools.protoc for sangam.proto
• emits sangam_pb2.py, sangam_pb2.pyi, sangam_pb2_grpc.py, and sangam_pb2_grpc.pyi
• uses mypy-protobuf for the gRPC .pyi file
• normalizes generated imports so the checked-in files work from the sangam.proto package without manual edits

If the script reports a missing plugin, run uv sync --dev first.
