[Bug] Excessive memory consumption with multiple subagents causes system hang

Bug Description
Claude code requested 26GB of memory and hanged my terminal, forcing a complete force-crash and losing work progress. Happened while running multiple subagents. Ideally subagents should just crash rather than requesting more memory than exists on the device.

Environment Info

• Platform: darwin
• Terminal: ghostty
• Version: 2.1.71
