Clean up CI Workflow (Node Version Warnings + Type Check Fail)

- setup-node@v4 uses Node v24 by default, triggering warnings by
  declaring v22. Developer and CI tooling is now unified through
  .nvmrc, CI.yml, and package.json (Current Astro version requires
  a minimum of 22.12.0 which is documented in package.json;
  node 24 is the most recent LTS which, used in CI and local dev)

- Type checking in Astro assumes that artifacts in .astro/ are
  available; references in source ts files are connected to
  these artifacts so tsc throws errors without them.
  So, `astro sync` must be run before typechecking
  in CI which creates the artifacts in `.astro/`. For convenience,
  `astro sync` is added to the `typecheck` npm script so it works
  in dev environments and CI.
