Branch names
The worktree field fills itself from your prompt: a prefix picked by the first word, then the words that matter.
"Fix broken anchors in the redirect pages" becomes fix/broken-anchors-redirect-pages. The worktree folder uses -
for /.

Type in the field to name it yourself; it stops following the prompt once you do.
The first word picks the prefix; anything else gets default_prefix (feature; "" for none).
