[BUG] rerunning an SSH'ed terminal block doesn't rerun the commands

[eythian]

Bug Description

If you run a terminal block in an SSH context, the commands defined in that terminal block will only execute the first time. The second time it stops at the command prompt

Steps to Reproduce

1. create a runbook
2. make an SSH block that connects to host.example.com
3. below that, make a terminal block that contains a command, for example ls
4. run the terminal block, note that it works as expected
5. close the terminal block (^D or pressing the red stop button)
6. run the terminal block again

Expected Behavior

The command in the block will be executed again

Actual Behavior

The command prompt on the remote host is displayed, but the command is not executed. There is a new entry on the terminal from which atuin-desktop is launched:

Environment

• OS: Ubuntu 25.10
• Atuin Desktop Version: 0.2.18

(the killing pty messages seem to appear when a terminal is closed, which makes sense. The second one there was the attempt that just results in being on the command prompt with no execution having happened.)
