chore: bump GitHub Actions to Node 24-compatible versions

[TMHSDigital]

Phase 2 of #18 (Node 20 deprecation, deadline 2026-06-02). Uniform action version bumps across this repo's workflows. dependency-review-action remains at v4 due to upstream block (tracked in #32). DTD also bumps peter-evans/create-pull-request from v6.1.0 SHA to v8.1.1 SHA (preserves supply-chain pin convention).
