# Debug CLI exit code enforcement

## Summary
- Rolled `debug/__main__.py` back one revision and added exit code propagation when scenarios record errors in `map.json`.
- Added targeted pytest coverage for the new exit path along with helper assertions around the runner's error detection.
- Updated entry-point tests to ensure the CLI exits with code 1 on failure and 0 on success, mocking argument parsing to avoid heavy fixtures.
- Extended tooling configuration by ignoring generated debug outputs in Prettier, keeping `bun run check` green.

## Testing
- `.venv/bin/pytest debug/tests/test_debug_cli.py::test_run_reports_map_errors debug/tests/test_debug_cli.py::test_main_exits_with_code_one_when_errors debug/tests/test_debug_cli.py::test_main_allows_zero_exit_without_errors`
- `bun run check`
- `bun run test:log:linux` (fails due to pre-existing upstream issues documented in the log)
