fix(agent): load huge images — disable PIL decompression-bomb guard

Trusted local library, not an upload surface, so a legitimately large image
(90–95M px, operator-flagged) must load. PIL only WARNS at the 89M-px default but
RAISES DecompressionBombError at ~179M px, which would fail those jobs. Set
Image.MAX_IMAGE_PIXELS = None. (The agent works off individual extracted files —
curator's archive_extractor unpacks zip/cbz/rar/7z at import — so this is about
big single images, not archives.)
