Problem

test_cache_hit_skips_vlm times out consistently on main (43s > 30s limit) when running with pytest-xdist parallel workers.

Root Cause

perception_cache.py imports cv2 (OpenCV) at the module level. When tests run in parallel with pytest-xdist, the cv2 import can hang/deadlock, causing the 30-second timeout.

Fix

Add cv2 to the list of stubbed modules in tests/conftest.py. This ensures tests get a MagicMock instead of the real cv2, avoiding the import hang.

Verification

All 812 unit tests pass (previously 1 failed with timeout)
tests/conftest.py passes ruff lint

Changes

tests/conftest.py: Added "cv2" to the stubbed modules list

Add 'cv2' to the list of stubbed modules in conftest.py to prevent
OpenCV import from hanging under pytest-xdist parallel workers.

The perception_cache.py module imports cv2 at the module level, which
can cause deadlocks/hangs when running tests in parallel with pytest-xdist.
By stubbing cv2 in conftest.py, tests get a MagicMock instead of the
real cv2, avoiding the import hang.

Fixes #1336
