Root cause: tsx wrapper does NOT forward SIGTERM to its child node process. When McpClient.close() was called, only the tsx process received SIGTERM, leaving the playwright-mcp node and Chromium grandchild processes orphaned. Fix: capture the tsx PID and use kill(-pid, SIGKILL) in close() to atomically wipe the entire process tree (tsx → node → Chromium). This permanently fixes the playwright browser leak issue where sessions accumulated 30+ orphaned Chromium processes over time.
- Add guard in shouldDebate() to check messages existence before accessing length - Use Array.isArray() in decide() for safer type check on input.request.messages - Fixes: Cannot read properties of undefined (reading 'length')
