Pull compositions from the deal until the expanded catalog ships

The composition pool (stagings) is not ready: too thin to help, and its
draws crowd the decision it rides along with. concept-seed.mjs stops
rendering the staging block by default; IMPECCABLE_COMPOSITIONS=1
re-enables it for catalog development, and the draw machinery,
rating-weighted selection, and mode scoping stay intact and tested for
its return. new-work.md drops the dress-the-staging-challengers
instruction and the FORM contract's staging clauses; the surface-scope
roll still assigns which of the model's own structures gets built.
