What's Wrong?

Hi,

I'm using latest claude native build on Windows.

I noticed high memory usage for no apparent reason, and here is info if I just start claude without doing anything (It consumes 4GB):

C:\Users\klo> pslist -m | findstr claude
claude            17016 4194303  249444 4194303 4194303   119332     22  428

I have it installed also as native build on WSL2, and there is no such issue (180MB):

$ ps aux | grep claude
klo       313353  4.0  2.3 74353564 191148 pts/6 Sl+  13:10   0:04 claude
klo       313714  0.0  0.0   7008  2304 pts/5    S+   13:12   0:00 grep --color=auto claude

$ cat /proc/313353/statm
18588391 47772 12128 14577 0 16784587 0

What Should Happen?

It shouldn't consume so much memory
