What's Wrong?
Claude Code shows extreme native memory leak (911 GB/hour growth rate) and Dispatch bridge stuck in "Asleep / Can't reach your desktop." EventEmitter memory leak warnings appear in logs.
What Should Happen?
Memory usage should remain stable during normal operation. Dispatch bridge should maintain connection without accumulating listeners.
