This fix addresses a critical bug where copyObjectByKeys would attempt to recurse into null values due to JavaScript's typeof null === 'object' quirk. The function now explicitly checks for null before recursion. Also includes comprehensive test suite for copyObjectByKeys and adds a test case documenting issue platformatic#70 (currently skipped as it requires architectural changes to support entity resolution for entities nested within entity resolver results).
