Subject: [PATCH] fix: bump 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). The action and workflows still
pinned Node-20 JS actions, which now emit deprecation warnings and
risk breakage.

Pins each action to its latest floating major tag that runs on Node 24
(verified against each action's action.yml `runs.using`):

- actions/checkout@v4 -> v5
- astral-sh/setup-uv@v3 -> v7   (no floating v8 tag published; v7 is node24)
- actions/setup-node@v4 -> v6   (+ build Node 20 -> 22 LTS)
- actions/upload-pages-artifact@v3 -> v5 (composite)
- actions/deploy-pages@v4 -> v5

Resolves #16.
