fix(tests): enable automation test discovery in pytest

The pytest configuration was excluding all "scripts" directories from
test discovery, which prevented 108 automation tests in
tests/unit/automation/scripts/ from running in CI.

Changes:
- Updated norecursedirs to specifically exclude .github/scripts instead
  of all "scripts" directories
- This allows test discovery in tests/unit/automation/scripts/

Impact:
- Automation tests now run in CI (+108 tests)
- Automation coverage increased from 0% to 61%
- Total test count: 492 → 600

All 108 automation tests pass successfully.
