tag releases with versions

[truedat101]

I'm happy to help you on release engineering. While master-commitref is probably useful for a customer or some internal project, humans want some meaningful release tags they can track, either a semer type version, or some tag name that is memorable. Sometimes people like to use a CI to generate release tags, but this is often an abuse of what tags are for. Since we treat tags as an immutable record (one cannot commit additional things to a tag), it is a great way to say,"Things were working well at X.Y.z" and this is what got put out.

Let me know if you want to go a different direction on release tagging, branches, etc.
