Run Velvet's EditMode or PlayMode suites headlessly and read the results correctly. Use whenever a change needs verifying against the test suite, or when a reported pass/fail count needs to be trusted.
Cut a Velvet release — close the CHANGELOG, bump the package version, dispatch the UPM workflow, and verify the published release. Use whenever a release, a version bump, or a tag is asked for, and when a published release needs its notes checked or repaired.
