ci: bump all GH actions to Node-24 majors + add Dependabot

The Node 20 → 24 cutover is coming (forced June 2 2026, removal
Sept 16 2026). Every action we use already has a Node-24
major released — we were pinned to stale ones, hence the deprecation
warnings in the prior runs:

  actions/cache@v4              → @v5
  actions/upload-artifact@v4    → @v7
  actions/download-artifact@v5  → @v8
  actions/github-script@v7      → @v9
  docker/build-push-action@v6   → @v7
  docker/login-action@v3        → @v4
  docker/setup-buildx-action@v3 → @v4

The big leaps (artifact actions v4→v7, github-script v7→v9) are
because the maintainers cut MULTIPLE majors between Node 20 and
Node 24; we're just catching up.

Also enable Dependabot for github-actions on a weekly cadence so
we don't drift again. Submodule + Rust deps explicitly NOT
auto-updated — they need careful audits.

Bumps to v0.1.3 to exercise the upgraded actions end-to-end.
