Suggestion: revise the installation flow about dorothy HOT 4 CLOSED

I'm thinking installation should come down to:

Which shells would you like to configure for Dorothy?

• bash
• zsh
• fish
• nu

How would you like to configure your shells? (Backups will be made, so don't stress.)

• Replace your shell's configuration to load Dorothy; use this if Dorothy is your first or only dotfile experience on this machine.
• Extend your shell's configuration to load Dorothy; use this if Dorothy is not your first dotfile experience.

Either technique will copy the original dotfiles to a xdg state directory for dorothy/shell-configuration-backup/time

Then they can run dorothy restore and dorothy uninstall to restore the original configuration on their machine.

Another improvement to do in this batch, is if installing dorothy and there is no user directory, then just rm rf dorothy directory and clone fresh in case there is an issue with the clone.

I'm thinking the installer should just ask what shells to configure and always do the extend method. The clean/replace method is too risky to expose to inexperienced users, and should just be enabled somehow for all-in dorothy users, either via a install flag such as install?clean=true or dorothy install --clean, or have dorothy support a configuration file (though to justify that, there should be more things to configure).

the other option is to maintain a database of default shell configuration files, so we can just wipe ones that are untouched.
