Subject: ci: add GitHub Actions workflow

There was no CI: the suite, byte-compile, and lint only ran when I ran them locally, so a regression could land on main unnoticed until the next manual run. This adds a workflow that runs make compile, make lint, and make test on every push to main and every PR, across Emacs 27.2 through 30.1 (27.1 is the package floor). An advisory snapshot job surfaces upcoming-Emacs breakage without blocking a merge. The README carries a status badge.
