Avoid checking out a branch already attached to a worktree

This recovery command will fail in the exact scenario this section targets: when a reusable worktree already has <target-branch> checked out. In Git, git checkout <target-branch> from the main checkout errors if that branch is already in another worktree (fatal: '<branch>' is already used by worktree ...), so the documented fast-forward path cannot run and the recovery flow stops. Update the instruction to fast-forward from the existing worktree path (or via a branch-ref update that does not require checking it out in main).
