## Summary by cubic
Parameterized the undo e2e test to run with and without native Git,
improving coverage without duplicating code.

- **Refactors**
- Added runUndoTest(po, nativeGit) helper and passed nativeGit to setUp.
  - Split into two test cases: “undo” and “undo with native git”.
- Minor whitespace-only formatting updates in snapshot and fixture
files.
