Expand concept system: modes, ratings, re-roll, breadth strategy

Catalog: mode-aligned staging surfaces (persuade/operate/read/experience),
star ratings on approvals feeding challenger draw weights, family
retirements, authoring strategy and territory guide, rework and breadth
authoring rounds, composition mining from rejected worlds.

Seed: six challengers (two per tier), --reroll chains, --mode staging
filter, rating-weighted draws. New-work: Present/visualize/re-roll flow,
image-gen requirement, register-neutral vocabulary.

Pipeline: per-mode staging prompts with split frames, hero-from-board
reference generation, render-safety guards. Labs: ratings UI, unrated
filter, mode chips, composition approve-guard.
