Move the slop defects back into the craft floor

The detector-blind slop review existed because the AI-tell rules had been
stripped out of SKILL.md and nothing carried them. The floor is a better
home: it loads after concept ideation and immediately before editing UI,
which is the placement that made stripping them necessary in the first
place. Models tread lightly when a ban list is present during ideation;
by the time the floor loads, the direction is already committed.

- Rename build-floor.md to craft-floor.md and restore the absolute bans
  (side-stripes, gradient text, glassmorphism, hero-metric, identical card
  grids, eyebrow-on-every-section, numbered markers, text overflow), the
  codex and gemini defect lists, and the reflexes no scanner catches.
  Rule ids match the ones the ablation catalog already knows.
- Delete lib/slop-review.mjs and both injections. The Stop hook is now
  purely a mechanical pass and stays silent with nothing to report.
- context.mjs replaces AI_SLOP_REVIEW_REQUIRED with the narrower
  MANUAL_DETECTOR_REQUIRED, emitted only when a session has no hook at
  all. A per-edit hook already covers the mechanical gap, and the floor
  covers the judgment one either way.
