Deleted chat_editor_test.exs and import_editor_test.exs which only checked function_exported?/Code.ensure_loaded? without exercising any behavior — both components are already tested via LiveView rendering in shell_live_test.exs and import_shell_live_test.exs respectively. Added TESTAUDIT.md documenting the procedure for periodic test suite audits to catch non-behavioral tests. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
