* fix(publish): advance @next dist-tag after stable release
When a stable release publishes via workflow_dispatch, @latest can leapfrog
the existing @next prerelease (e.g. latest=6.5.0 while next=6.4.1-next.0),
turning `npx bmad-method@next install` into a silent downgrade until the
next qualifying push to main republishes a fresh -next.0.
- publish.yaml: after stable publish, repoint @next at the just-published
stable version. The existing derive-prerelease step picks max(latest, next)
as its base, so subsequent push-driven prereleases bump from there.
- bmad-cli.js: checkForUpdate was querying the @beta dist-tag (which this
package does not use). Replace string-matching with semver.prerelease()
and query @next for prerelease users.
* fix(publish): harden next-tag advance step and broaden path filter
- continue-on-error on the dist-tag advance: failure leaves @next stale
until the next push-driven prerelease, which is recoverable; failing the
job after a successful publish + git tag + GH release is not.
- Status echo so release-log triage can confirm the advance ran.
- Add removals.txt to the push-trigger path filter. Installer-affecting
changes outside src/** (like the post-6.5.0 removals.txt fix) should
still trigger a fresh -next.0 publish.
