chore(guard): sync vendored public-repo-guard to canonical

[wave-av-release-bot]

Syncs the vendored public-repo-guard trio to the canonical source in wave-foundation/scaffolder/public-repo-guard.

• adds the internal-ip leak rule (Tailscale-CGNAT 100.64.0.0/10), lockstep with the pre-publish mirror gate
• reconciles accumulated drift in the vendored copy

Each changed file is byte-for-byte identical to canonical (verified by git blob SHA). The repo's own Secrets + content policy gate re-scans this PR.

Note

Update public-repo-guard workflow to use actions/checkout v7 without persisted credentials

Syncs public-repo-guard.yml to the canonical version. Upgrades actions/checkout from v5.0.1 to v7.0.0 and sets persist-credentials: false so the GITHUB_TOKEN is no longer stored in the repository's Git config after checkout.

Summary by cubic

Syncs the vendored public-repo-guard with the canonical wave-foundation/scaffolder/public-repo-guard to remove drift and tighten secrets/content scanning. All files are byte-identical to canonical.

• New Features

  • Add internal-IP leak rule for Tailscale CGNAT 100.64.0.0/10 to match the pre-publish gate.

• Dependencies

  • Upgrade actions/checkout to v7.0.0 and set persist-credentials: false to avoid persisting the job token during the gitleaks scan.

Approvability

Verdict: Needs human review

Unable to check for correctness in 371f5e7. This CI workflow change (checkout version bump + credential hardening) is owned by wave-av/core-team, but the PR author is a bot that does not own this file. CODEOWNERS designates the core-team as the appropriate reviewers for workflow changes.

🔍 Checkout pin now inconsistent with other workflows in the repo

This workflow now pins actions/checkout to v7.0.0 while .github/workflows/_checks.yml:23,54,114 still pin v4.3.1 and .github/workflows/test.yml:17 uses the unpinned floating tag actions/checkout@v4. Not a defect in this PR (the guard workflow is deliberately vendored/self-contained), but the unpinned usage in test.yml is inconsistent with the repo's pinning convention and worth a follow-up.
