fix: complete spawn chain — market_research→design, design→reviews+roundtable

Closes the two broken links in the incubation pipeline:
- market_research now spawns company_design (Phase 1→2)
- company_design now spawns 4 design_reviews + design_roundtable (Phase 2→3/4)

Also: cleaned up design_review to use identity-driven review instead of IF/ELSE blocks
