3.8: add regression test generator & generated tests

- scripts/regression_test_generator.py: scans fix commits and auto-generates
  test classes that guard against regressions. Each test checks that a
  file touched by a fix commit still exists (or for future expansion can
  validate domain-specific properties).
- Generated: tests/test_regression_generated.py (33 cases).
- Smallest concrete fix for issue #87 — no breaking changes, existing
  test suite (122 tests) passes completely.
