nekomimi.petfeat: multiple images, collapsed pastes, and an attachment strip in the prompt6e828112026-10-04

// Which terminals get thumbnails depends on the environment and, under tmux,
// on the attached client and a tmux option; the e2e suite runs in neither, so
// a wrong branch here would only show as missing or garbled thumbnails.
