Vouch request: Dattuog — Fix SSH connection sharing (#3935)

[Dattuog]

What do you want to work on?

I want to fix issue #3935: #3935

When SSH connection sharing is enabled, OpenShell can reuse a connection to another sandbox. Commands or uploaded files may then reach the wrong sandbox.

I’ve prepared a fix that disables connection sharing for sandbox connections and generated editor configurations. It includes two regression tests, and all 51 SSH tests passed.
The change is available here:
Dattuog@987b826

Why this change?

Users should be able to trust that their commands and files reach the sandbox they selected. I picked this issue because it affects normal CLI usage and has a clear, focused fix. I’d like to contribute the change and address maintainer feedback.
