# Build, lint, and test gate for the whole workspace on a clean runner.
# The Dockerfile proves the rustyred-server binary builds; this proves every
# crate compiles, lints stay clean under -D warnings, formatting is enforced,
# and the test suite passes. protobuf-compiler is required because
# crates/rustyred-server/build.rs compiles vendor/proto via tonic-build.
# The vendored proto is in-tree, so no submodule checkout is needed.
