Enforce Angular Commit Message Guidelines within GitHub.

I need to see if such a linter already exist (as a GitHub Action would be ideal)

The most popular GH Action appears to be https://github.com/wagoid/commitlint-github-action.

There's a simple GH App here: https://github.com/zeke/semantic-pull-requests.

cool, thanks for the links @moorereason! I'll give it a try soon

Is there some meaningful tooling that consumes these commit messages? TBH I really find them to be kind of a pain -- I've not seen them used anywhere else before.

yes, I generate the changelog that appears on https://github.com/bytesparadise/libasciidoc/releases using https://github.com/conventional-changelog/conventional-changelog and it parses the commit message to determine the type commit it was, and the scope.
