bash tool can return before output capture completes

[MaartenBaert]

Description

The bash tool consumes process output in a scoped background fiber, but returns after handle.exitCode without joining that fiber. Closing the scope can interrupt output capture before buffered stdout or stderr is added to the result, causing a successful command to intermittently report (no output).

Plugins

none

OpenCode version

1.17.18

Steps to reproduce

This is a rare race condition, I do not have a procedure to reproduce it reliably.
