Fix CI Node 20/22 floors to match vite/rolldown's actual requirement

vitest 4 pulls in vite 8, which bundles rolldown and requires Node
^20.19.0 || >=22.12.0. The prior 20.15.1 test lane was below that
floor, so npm skipped installing rolldown's native binding in CI
(the underlying cause was the Node version, not a lockfile bug).
Align engines and the CI matrix to the versions vitest actually needs.
