+### Changed

+- **Bumped GitHub Actions to Node 24-compatible versions** — GitHub forces Node 24 as the default runner runtime from 2026-06-02 (Node 20 fully removed 2026-09-16). Updated `actions/checkout@v4→v5` and `astral-sh/setup-uv@v3→v7` in `action.yml` and CI; the docs workflow now uses `actions/setup-node@v4→v6` (Node 22), `actions/upload-pages-artifact@v3→v5`, and `actions/deploy-pages@v4→v5`. Resolves #16.
