feat: enable cacheScripts and add cache miss scenario in e2e tests

- Enable `cacheScripts: true` in patch-project.ts after migration so
  `vp run` commands exercise the task cache hit/miss code paths.
- Add a third "cache miss" run to the e2e workflow that modifies
  package.json between runs to trigger PostRunFingerprintMismatch.

The e2e flow is now: first run (cache miss NotFound) → second run
(cache hit) → invalidate → third run (cache miss FingerprintMismatch).
