Release / build-and-push (push) Successful in 3m1s
The version tag previously existed only in git and the Docker image tag — the running app had no way to report what build it was. Version is now injected at build time via -ldflags into internal/version.Version (defaults to "dev" for local builds), passed by the release workflow as the APP_VERSION Docker build arg from the pushed tag. Surfaced in Admin → Settings → About (extensible card for future rows like disk space) and in the /health JSON response, so deployments can be verified with curl alone.
