actop 1.6.9

Added

• Guard-release CI workflow (guard-release.yml): every v* tag push verifies
  all tags have a corresponding GitHub Release object, failing the run if any are
  missing — catches the silent link breakage that caused the v0.8.7–v1.6.6
  release-object gap.
• Pre-push githook tag nudge: warns when a bare git push of a v* tag is
  detected, reminding to use scripts/tag_release.sh instead.

Changed

• README badge row gains a Website badge linking to the Cloudflare Pages coverpage
  (actop.pages.dev).
