publish-npm and create-release now checkout the same ref as
build-and-test (the input tag or push ref), preventing source
mismatch between npm package and GitHub Release artifacts.
1. npm version check: three-state logic (exists/missing/error) to prevent
silent skip on network failures, registry 5xx, or auth issues.
2. workflow_dispatch: checkout the specified tag and validate SHA matches,
preventing builds from wrong ref.
3. Atomic push: use `git push --atomic` and detect unpushed tags via
`git ls-remote` instead of `--no-merged` (catches branch-pushed-but-
tag-failed state).
1. Update release-cli.yml to make create-release depend on publish-npm with proper skip_npm handling, preventing half-released state where GitHub Release exists but npm package is unavailable.
2. Rewrite publish-cli-test.sh to cover the new publish flow: main branch check, dirty tree detection, tag baseline sync, version bumping, tag conflict detection, user cancellation, and atomic push verification.
- Add release-cli.yml GitHub Actions workflow: build, test, npm publish,
and GitHub Release triggered by cli-v* tags
- Rewrite scripts/publish-cli.sh: local bump + commit + tag + push,
enforces main branch, idempotent tag checks
- Add concurrency group and release idempotency to workflow
- Add make publish-cli / publish-cli-minor / publish-cli-major targets
- Add cli/RELEASE.md documenting the full release process
