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.

Summary by cubic

Syncs the vendored public-repo-guard with wave-foundation/scaffolder/public-repo-guard. Adds the internal-ip leak rule for Tailscale CGNAT (100.64.0.0/10) and hardens the scan workflow.

• Dependencies
  • Bump actions/checkout from v5.0.1 to v7.0.0.
  • Set persist-credentials: false so the job token isn’t available during the gitleaks scan (no git push needed).

Approvability

Verdict: Needs human review

Unable to check for correctness in dd0fd4d. This CI workflow update (checkout version bump + persist-credentials security hardening) is low-risk, but the changed file is owned by wave-av/core-team and should be reviewed by the designated owners.
