Tag Release

Suggest and apply the next semver tag based on commits since the last tag.

Note: For team repos or any repo with a CI/CD pipeline, automated tagging via a pipeline (e.g. GitHub Actions triggered on merge to main) is strongly preferred over running this command manually. Use this command for solo projects or when no pipeline is set up.

Steps:

1. Run git tag --sort=-version:refname | head -1 to find the most recent tag. If no tags exist, suggest v0.1.0 as the first tag.
2. Run git log <last-tag>..HEAD --oneline to see commits since the last tag. If there are no commits since the last tag, tell the user there is nothing to release and stop.
3. Determine the next semver version:
   • Bump major if any commit contains BREAKING CHANGE
   • Bump minor if any commit is type feat
   • Bump patch for all other changes
4. Show the user the proposed tag, the version bump reason, and the list of commits that will be included.
5. Ask the user to confirm before proceeding.
6. On confirmation, run git tag <version> to create the tag, then git push origin <version> to push it.
7. Confirm the tag was pushed and print the tag name.
