Walkthrough

Adds a new Go-based protoc plugin (protoc-gen-elixir-grpc) with tests and README. Updates Taskfile to build both Go and Elixir plugins, generalizes .gitignore patterns for protoc-gen-* binaries, and registers the new plugin in release-please config. No other control flow outside the new plugin.

Changes

Cohort / File(s)	Summary
Release config .github/.release-please-config.json	Adds cmd/protoc-gen-elixir-grpc package entry with component protoc-gen-elixir-grpc.
Build tooling & ignores .gitignore, Taskfile.yml	Generalizes ignore patterns to protoc-gen-* and protoc-gen-*.wasm. Updates build-plugin description/output; adds build-plugin-go and build-plugin-elixir tasks that build respective binaries.
Elixir gRPC plugin cmd/protoc-gen-elixir-grpc/README.md, cmd/protoc-gen-elixir-grpc/main.go, cmd/protoc-gen-elixir-grpc/main_test.go	Introduces new protoc plugin generating Elixir gRPC server modules with defdelegate handlers; supports parameters (package_prefix, handler_module_prefix), version/help, error reporting. Adds comprehensive tests and usage docs.

Poem

A rabbit taps keys with a gentle thrum,
New plugin hops in—Elixir, here we come!
Tasks multiply, binaries bloom,
Globs sweep trails with a tidy broom.
Protoc whispers, handlers reply—
Code carrots harvested, outputs fly.
Hippity-hop, ship it high! 🥕🚀
