Flesh out per-style negatives in smart_image_gen Tool

Each style now gets a proper baseline covering quality, anatomy, and
watermark/signature suppression — plus the appropriate style-leak guards
(no-cartoon for photo, no-human for furry, score_4–6 suppression for
pony). Quality terms only; no NSFW filtering by default since several
checkpoints in this set are commonly used for adult work and would
fight a baked-in content filter. If SFW-by-default is wanted, add an
explicit safe-mode flag rather than expanding NEGATIVES.
