Track four test files that were never committed

CLAUDE.md cites tests/test_model_config.py as the guard against reintroducing
retired OpenRouter model ids, but the file existed only on disk — the guard was
not in the repository. Same for the town geo, voice roster and voicemail
transcript tests, and the Reaper bleep-selection test.
