Subject: [PATCH] python3Packages.protobuf-py: init at 0.1.1

Buf's idiomatic Protocol Buffers runtime for Python, required by connectrpc
and the E2B Python SDK.

Fetched from PyPI because upstream has no tag for this release; its only tag
is v0.2.0, which neither connectrpc nor e2b accepts yet.

Assisted-by: Claude Code (Claude Opus 5)
