feat: add Lima VM E2E tests and fix princeprocessor build

Add Ubuntu 24.04 Lima VM test track that runs hate_crack installation
end-to-end in a real VM, giving higher confidence than Docker-based tests.

- Add lima/hate-crack-test.yaml: Ubuntu 24.04 VM config with hashcat and
  build deps pre-installed via apt; uv installed via official installer
- Add tests/test_lima_vm_install.py: mirrors Docker E2E test structure;
  uses rsync with targeted excludes (wordlists, compiled host binaries)
  and builds wheel directly to avoid setuptools-scm sdist file filtering
- Fix Makefile: add princeprocessor build step with aarch64-compatible
  CFLAGS (drops -m64); copy binary to submodule root for vendor-assets
- Add Lima tests to prek.toml pre-push hook
- Document Lima VM tests in TESTING.md
