Hatch Protobuf Plugin

Hatch-protobuf is a Hatch build plugin designed to automatically generate Python files from Protocol Buffers (.proto) definitions. It leverages `grpcio-tools` internally to invoke the `protoc` compiler, streamlining the integration of Protobuf schema compilation into the standard Python build process. As of version 0.5.0, it is actively maintained, though its release cadence is tied to the broader Hatch and Hatchling ecosystem.
