Opencode hangs on node 20

[martinalderson]

On node 20 opencode hangs with run commands in CLI mode. Some other commands do work though. I'm struggling to get a solid repro (I'm using it in a docker container) but it works perfectly in node 24. It seems to be hanging after opening a port.

It may be something else, but is it meant to work on node 20 or not? If so it would be good to fail quickly.

Mine hangs when I try to exit. I have to ctrl+c another time.
