* Code refactoring and clean up

* Remove accidentally added submodules

* Specify folder destination

* Remove default worktree path, always prompt for destination instead

* create worktree only displayed in repo's worktree subcommands

* Git - handle another error condition when detecting worktrees (#256278)

* Rework creating worktree flow

* Include worktree name placeholder
