fix: agent template mappings + roundtable sections injection

Critical: Peter was missing design_review — spawned tasks would go unclaimed.
All 4 agents now have design_roundtable in supported_templates.
Removed design_polish from Peter (Elena does polish, not Peter).
Added sections block to design_roundtable for deliverables/RAG access.
