- promote.sh: fail fast before mutating the public tree if the tag was already
promoted (avoids a half-commit left on the runner on re-dispatch).
- ci-staging.yml: pass STAGING_PROJECT_DIR via env + :? guard instead of a
${{ }} expression in run: (clears the template-injection lint, fails loudly
on misconfig).
- README: PUBLIC_REPO_URL was never read by any workflow — keep only the slug.
- set-repository-url.test.sh: chmod +x for mode parity with promote.test.sh.
