Add a parameter for `--closeOnExit`

[htcfreek]

Description of the new feature/enhancement

You can sett e keep open parameter as parameter of the shell used. But if this Is dynamic (e.g. in PowerToys shell plugin) a global parameter for WT would be helpful.

This parameter should keeps the WT window open regardless of the choosen profile and its parameters.

Proposed technical implementation details (optional)

Sorry could you elaborate more/? What exactly do you mean by "keep open"? Like, "always on top"? Or do you mean something more like "keep running even after I've closed all windows"? Or something else entirely? I'm not sure I'm totally familiar with all the powertoys these days 😝

What I mean is a wt.exe parameter like cmd /k or powershell -NoExit that works on all profiles regardless off the profile/shell.

Use case: Shell plugin of PT Run. The window should stay open to show the results. (Currently we need some tricks to keep the command results visible which lead to microsoft/PowerToys#28876.)

Oh, so like, a wt command-line version of "closeOnExit":"never"?

Er, well, reading that closer, that might not be quite right. -NoExit isn't just "leave the window open after the command completes", it's "Return to the shell prompt after the command exits". I'm pretty confident that can't be done in a general-purpose way.

Like, for cmd.exe, that would be cmd.exe /k {{command}}, sure. But what if the user's commandline is set to ssh? What if it's just ping.exe 8.8.8.8? wsl.exe tmux -a?

If the goal is just to leave the output on the screen after the command exits, that's easy enough to add with --closeOnExit=never or whatever. But returning to the shell is probably impossible, without manually setting the commandline to something like cmd.exe /c {command} & {shell} (which I'm sure is fraught with string excaping nightmares and other edge cases).

The main goal is to keep the window open for reading the output. So --closeOnExit=nerver or even much easier --keepWindowOpen is what we need.
