chore: unused 'from unittest import mock' in test_parse_instinct.py

## Summary In `skills/continuous-learning-v2/scripts/test_parse_instinct.py` line 22: ```python from unittest import mock ``` This import is unused. The test file uses `monkeypatch` (pytest's built-in fixture) for all mocking needs. `mock` is never referenced via `mock.patch`, `mock.MagicMock`, or any other `mock.*` usage. ## Suggested fix Remove the unused import: ```diff -from unittest import mock ```
