microsandbox-rb

Cut a release of the microsandbox-rb gem — walk the version lock-step SOP and tag vX.Y.Z to trigger the OIDC publish. Usage: /release <version> (e.g. /release 0.5.10). User-triggered only.

Run the full local check gate for this gem — cargo fmt --check, cargo clippy -D warnings, standardrb, and the unit specs (optionally integration). Use before pushing, opening a PR, or claiming a change is done. (The bundled /verify skill — run the app and observe behavior — still exists and is separate.)
