shell commands can break visuals

[rmburg]

Summary

when running a shell command like fzf which clears the screen or does other things to the terminal, things break a bit:

• helix does not rerender after the shell command exits, causing leftover visuals from the shell command
• when exiting helix in this state, the last output from helix sticks around in the terminal

Reproduction Steps

1. open helix
2. run :insert-output fzf
3. close fzf
4. observe breakage
5. run :redraw
6. observe: everything looks normal again
7. quit helix
8. observe: output is not cleared as it should

invoking TUI programs from helix is not supported. All shell related functionality is only meant for non-interactive commands. Intreactive commands will only work once we have a builtin terminal emulator (and probably still not with :insert-output).
