Move unit tests from tests/unit/ to internal/ following Go conventions:
- tests/unit/logging/* -> internal/logging/* (logging tests)
- tests/unit/manifest/* -> internal/manifest/* (run_manifest, schema tests)
- tests/unit/network/* -> internal/network/* (retry, ssh_pool, ssh tests)
- tests/unit/privacy/* -> internal/privacy/* (pii tests)
- tests/unit/metrics/* -> internal/prommetrics/* (metrics tests)
Update import paths in test files to reflect new locations.
Note: metrics_test.go moved from tests/unit/metrics/ to internal/prommetrics/ to match the actual package name.
Reorganize tests for better structure and coverage:
- Move container/security_test.go from internal/ to tests/unit/container/
- Move related tests to proper unit test locations
- Delete orphaned test files (startup_blacklist_test.go)
- Add privacy middleware unit tests
- Add worker config unit tests
- Update E2E tests for homelab and websocket scenarios
- Update test fixtures with utility functions
- Add CLI helper script for arraylist fixes
