Can confirm the memory leak is quite bad on Windows. Typically have to kill OpenCode every 30 minutes (on a 32gb machine).

Just had a long-running prompt (i18n extraction in a codebase) that only did file reads and file writes for a period of time. This alone was clearly leaking as the Bun process raised from initially ~500mb memory to ~1,3gb in a few minutes, and still climbing.

I'm using OpenCode on Windows 11 with PowerShell 7. After launching OpenCode, even if I don't initiate any conversation, the memory usage keeps increasing until it completely cripples my system. From Task Manager, I can see that numerous PowerShell processes are being spawned continuously, and new ones keep launching nonstop. I don't understand what's causing this issue.
