[BUG] Claude Code desktop app consuming 36GB RAM, crashes repeatedly after update

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

After updating to the latest version, the Claude Code desktop app has crashed twice within 30 minutes due to running out of application memory. macOS shows the "Force Quit Applications" dialog with Claude using 36.31 GB of RAM.

What Should Happen?

Memory usage should stay within a reasonable range (typically under 2GB for a normal session). The app should not grow heap unbounded or trigger macOS out-of-memory warnings.

Error Messages/Logs

macOS system dialog:
"Your system has run out of application memory.
To avoid problems with your computer, quit any applications you are not using."

Activity Monitor reading:
Claude — 36.31 GB

Steps to Reproduce

1. Update Claude Code desktop app to v2.1.114
2. Open the app and start a normal conversation session
3. Use it for regular tasks (chat, code edits) for ~15-30 minutes
4. Observe memory usage in Activity Monitor climbing continuously
5. Eventually macOS shows the "Force Quit Applications" out-of-memory dialog
6. App must be force-quit; happens repeatedly (twice within 30 minutes in my case)
