/**
 * @file AddLaneModal.test.tsx
 * @description Pins the "+ Add lane" flow's two modes: "Worktree" (default -
 * pick a source repo, fork a branch, type a new branch name, submit through
 * the provisioning endpoint) and "Repo" (adopt a directory as-is through
 * `ensure`, no branch fields). Also covers the branch-lookup debounce, the
 * unresolvable-path degrade, server-error handling, the auto-setup summary,
 * the provisioning-wait race, and the folder-browse modal.
