Title: Critical Memory Leak - claude.exe consumes 4.7GB RAM during task execution
Bug Report:
## Environment
- Claude Code version: 1.0.102 (latest)
- OS: Windows 11
- Installation: npm global install
## Issue Description
Claude Code has a severe memory leak where claude.exe consumes massive amounts of RAM (4+ GB) during normal task
execution, making the entire computer unusable.
## Steps to Reproduce
- Start Claude Code fresh (computer was completely off before starting)
- Ask Claude to perform any task
- Computer becomes completely unresponsive due to memory usage
- Check Task Manager - claude.exe shows 4,744,420 KB (4.7GB) memory usage
## Expected Behavior
Claude Code should use reasonable amounts of memory and not freeze the entire system
## Actual Behavior
- claude.exe process balloons to 4+ GB RAM usage
- Computer becomes completely unresponsive
- User has to "start typing on keyboard" to get any response
- System stutters and freezes during task execution
## Additional Context
- This is NOT leftover processes from previous sessions
- Happens immediately when starting fresh and requesting tasks
- Memory usage was verified with wmic command during active session
- Makes Claude Code completely unusable on this system
## Urgency
CRITICAL - Tool is completely unusable due to this memory leak
