protoc support

[steeve]

Hi,

First of all, congratulations, this looks great! Would you be open to protoc support? It's mostly https://github.com/protocolbuffers/protobuf/blob/main/src/google/protobuf/descriptor.proto on stdin and file contents on stdout.

This would ease support for other build systems, most notably regarding well known types.

Cheers,

Thanks for the feedback! 👋 Just to break this down clearly - we're looking at two key pieces:

• A protoc-style binary that handles proto -> zig
• protobuf "stdlib" (for well-known types) in gremlin library module
