v4.1.19

What's Changed

Bug Fixes

• engine: Pre-flight reviewer blocking gate now fires on group-0 findings (#713) — two bugs prevented pre-flight reviewer (group 0) drift and review findings from triggering the blocking gate
• adk_tools: search_files now returns a structured error on nonexistent paths instead of silently returning empty matches
• tests: Fixed broken SDK import failure test using reliable sys.modules mechanism

Refactoring

• deps: Made deepagents and google-adk mandatory dependencies (previously optional extras), removing conditional import guards and pytest.importorskip patterns
