build(deps-dev): bump @types/node to 26 and vite to 8.1.5

Take the safe dev-dependency bumps from the development-dependencies group.
TypeScript is held at ^5.7.2 (resolves to 5.9.x) because the 7.0 major is
the native-compiler rewrite and breaks the package builds and typecheck.
Dev-only change, so an empty changeset records that no release is needed.
