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)

+      CHARACTER ARC UPDATE
+
+      A permanent change occurred for {character_name} in chapter {chapter_ref}.
+      Permanent change: {permanent_change}
+
+      Your tasks:
+      1. Read the RAG context for this character:
+         - Look for [character-{character_slug}] -- the static profile
+         - Look for [character-state] -- the current live state
+         - Look for [voice-signatures] -- the voice profile (if relevant)
+
+      2. Determine what needs updating:
+         - Append to the character's ## Arc Log: "Ch {chapter_ref}: {permanent_change}"
+         - If a POWER was gained or lost, update the ## Abilities section
+         - If a RELATIONSHIP status changed (e.g. enemies-to-allies, death),
+           update the ## Relationships section
+         - If VOICE changed (new speech patterns, trauma affecting language),
+           update the ## Voice Signature section AND flag voice-signatures.rag.md for update
+         - If MAGIC SYSTEM affinity changed, flag magic-system.rag.md for update
+
+      3. Write the updated full character profile:
+         - Keep all existing sections
+         - Only change the specific fields that changed
+         - Add the arc log entry
+         - Mark clearly at top: "Updated: Ch {chapter_ref} -- {permanent_change}"
+
+      Write the COMPLETE updated character profile now.
