Summary

The vitest@3 upgrade seems to have introduced significant e2e test flakiness on Windows (right when we've finally fixed integration test flakiness 😓).

This PR attempts to resolve this by reverting the e2e vitest pool to v1 config. See https://vitest.dev/guide/migration.html#default-pool-is-forks.

Also:

  • remove unneeded e2e vitest config
  • move deps.external to new (non-deprecated) location
