[Bug] Memory leak in agent execution causes rapid RAM exhaustion

Bug Description
For the past week I'm experiencing a horrific memory leak that fills my 32gb of ram in less than a minute. I think this happens when claude launches agents, but not sure (when I ask it to explore the codebase, review the code etc). This makes claude CLI basically unusable for me. Ran it in ghostty & in alacritty with same results.

Environment Info

• Platform: linux, debian 13
• Terminal: ghostty, alacritty
• Version: 2.1.100
• Feedback ID: d31fd0e4-d9ac-4a1d-8140-63d47a845304
