Enable zellij as multiplexer besides tmux

[derphilipp]

I want to suggest a new ste

No!

• Which tool is this about? Where is its repository?
  • Zellij, a tmux-style terminal multiplexer https://github.com/zellij-org/zellij
• Which operating systems are supported by this tool?
  • macos, linux, windows (wsl), etc.
• What should Topgrade do to figure out if the tool needs to be invoked?
  • n/a
• Which exact commands should Topgrade run?
  • No commands, but support to open up multiple remote connections, but instead of using tmux, use zellij.
• Does it have a --dry-run option? i.e., print what should be done and exit
  • n/a
• Does it need the user to confirm the execution? And does it provide a --yes option to skip this step?
  • n/a

I want to suggest some general feature

Topgrade should... ... be able to use zellij besides tmux as a terminal multiplexer. Zellij lives in the same realm of rust tools and would be an awesome addition;

Instead of using the GitHub issues page, you could consider posting your suggestion on the Topgrade discussions page at https://github.com/topgrade-rs/topgrade/discussions/categories/ideas. The discussions section is often a better place to share ideas and get feedback from the project maintainers and community.

This looks nice to have, Topgrade has a run_in_tmux configuration entry, if we have this implemented, it can be renamed to something like:

[misc]

# If set, Topgrade will be executed in the specified multiplexer. Otherwise, run in the current shell.
# Available multiplexers: ["tmux", "zellij"]
run_in_multiplexer = "zellij"
