Possible memory leak on OpenCode 1.2.15

[RyanGst]

Description

After using OpenCode for a while, I noticed multiple opencode processes remaining alive at the same time. Each process is holding an significant amount of memory.

Over time this looks like memory/process accumulation.

I also captured this in Activity Monitor, where multiple opencode processes appear at the same time:
