fix(release): drop the moving current tag; consumers pin release tags

Reverts the `current` half of #10 (the gpt-5.6-terra switch stays).
release.yml no longer force-moves a `current` tag; README documents pinning
a dated release tag (currently 1.32.20260826) and bumping deliberately.
The `current` tag itself is deleted from origin once every consumer PR
references 1.32.20260826.
