Releases

Every merge to main goes through releaser. A feat, fix, perf, refactor or docs commit cuts a patch release: it updates CHANGELOG.md, tags vX.Y.Z, creates the GitHub release with bercail-extension-X.Y.Z.zip attached, and publishes the image under that tag and latest. Pull requests publish a pr-<number> image, and their titles must be Conventional Commits because the squash merge uses them as the commit message.
