fix(ci): bump Node to 22.13.0 (pnpm@11 minimum)

The first CI run failed at `vp install`: pnpm@11.1.2 requires Node >=22.13, but
the workflow pinned 22.12.0 (the old engines floor). Pin 22.13.0 — the real
lowest Node the toolchain supports — and correct engines.node to >=22.13.0 so
the declared engine matches what pnpm actually needs.
