fix: test collection errors in test_bannerlord_harness and test_evennia_ws_bridge (#1509)

Resolves #1509. Two test files were failing to collect during pytest.

nexus/evennia_ws_bridge.py:
- Extracted clean_lines(), parse_room_output(), normalize_event()
  from playback() closure to module-level functions
- Tests import these as module-level symbols; they were buried
  inside the playback() function and inaccessible

nexus/bannerlord_harness.py:
- Fixed import: 'from bannerlord_trace' to 'from nexus.bannerlord_trace'

Results:
- pytest test_evennia_ws_bridge.py: 5 passed
- pytest test_bannerlord_harness.py: 37 passed, 2 skipped
- 44 tests now running that were previously broken
