1// Create (and optionally push) the ChronVer git tag for the current release.
2// The version is read from package.json; the tag is an annotated tag on the
3// commit that set it. Run this AFTER committing the release bump — pushing the
4// tag is what triggers the CI image build (.tangled/workflows/build-image.yml).
5//
6// deno task tag # create the annotated tag locally
7// deno task tag --push # also push it to origin (triggers CI)
