Sprint 56h: evolving character sheets + reliable injection

- Split project.rag.md into 6 focused RAG files (voice-signatures, magic-system,
  story-premise, factions, character-state, world-state)
- book_chapter.yml: PASS 0 STEP 5 replaced with live RAG character/world state check +
  location continuity validation; PASS 3 added for character+world state extraction after
  each chapter (rag_write -> character-state RAG + deliverable snapshot)
- chapter_polish.yml: PASS state extraction after final document (full-mode canonical state)
- book_outline.yml: added Factions section template with NPC memory model
- NEW character_update.yml: permanent arc change template (updates static char profile)
- chapter_review.yml: Sprint 56g voice authenticity fixes (fire/ice -> Body/Mind duality)
