In settings, please allow me to turn off worktrees globally, as some people might not use it at all. It should be a user preference.

Start by locating the app's settings entry point and the existing worktree handling. Add a persistent user preference that disables worktrees globally, then verify that the setting is respected wherever worktrees would otherwise be used.
