Subject: [PATCH] fix(rock): embed GARM version via git describe in ldflags

The garm binary was reporting v0.0.0-unknown because the build did not
inject version information. Use git describe at build time to extract
the version from the source-tag, matching upstream's Makefile approach.

This ensures renovate bumps to source-tag automatically propagate to
the embedded binary version without maintaining a duplicate variable.
