restricted mode (like rvim / rnano)

[LunarLambda]

For use by root / under sudo, or any situation where the editor being arbitrarily flexible is undesirable or problematic.

For reference, rvim / vim -Z disables:

1. All features that execute shell commands or otherwise spawn background jobs (in helix this would necessarily include LSP)
2. Suspending to the shell with Ctrl-Z
3. Scripting interfaces (in the future this might mean restricting APIs or disabling use of plugins altogether)
4. Interfaces that delete or rename files or create directories

I am aware of both the :w !sudo tee % >/dev/null trick, and sudoedit, but there's plenty of situations where neither is applicable (files that aren't world-readable, systems that don't use sudo, situations where you're already root anyway). I think a restricted mode is a low-stakes, low-maintenance, never-wrong-to-have feature.

Suspending to the shell with Ctrl-Z

why this?
