New internal/version package: ldflags-stamped Commit with a debug.ReadBuildInfo VCS fallback for host builds. Startup log line carries commit + Go version; --version prints the hash and exits. Makefile computes GIT_COMMIT (12 chars, -dirty on any local change) and passes it to docker-build/buildx; Dockerfile injects it via -ldflags and an org.opencontainers.image.revision label. make build now uses ./cmd — file-argument builds skip Go's automatic VCS stamp.
