Ship the final pet-generation UX polish (provider picker behavior, step-2 cancel flow, banner integration, and visual consistency) and make saturated-chroma background removal C-op driven so hatch processing no longer hammers the machine during long runs.
- pet.generate / pet.hatch (parallel rows, off the reader thread) +
cooperative pet.cancel; pet.export / pet.rename.
- pet.gallery localOnly fast path + background manifest prefetch so the
picker never blocks on petdex; rename follows the active-pet config.
- gateway request gains optional timeout + AbortSignal for real Stop.
