Lets Pathway (and other consumers) resolve dev.relism:flash from Gitea's
Maven registry instead of requiring a local `mvn install`. Every push
stamps all modules with a commit-scoped version (2.1.0-<short-sha>) before
deploying, since Gitea's registry won't let a build overwrite an existing
name+version.
