Creativity mask applies at all reward levels including Perfect

Removed reward >= 0.8 early returns from build_creativity_mask and
load_and_apply_creativity_mask. The global floor formula already handles
high reward correctly: at 1.0 it produces 0.0 floor, leaving only gentle
spatial variance (0-8% of latent std). A Perfect-rated latent is the best
possible reference - discarding it was wrong.
