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)

+## MAGIC SYSTEM — Body/Mind Duality (replaces all fire/ice metaphors)
+
+The Starfall Accord's magic is NOT fire vs. ice. That framing is FORBIDDEN in all chapter writing.
+The true duality is BODY (embodied practice) vs. MIND (disciplined will/intent):
+
+- MIRA'S SCHOOL (Ignis Academy) — Magic as embodied practice. Power lives in what the body already
+  knows: muscle memory, accumulated repetition, the intelligence stored in the hands and spine.
+  You don't think the spell; you have already done it ten thousand times.
+  Mira's power is improvisational, adaptive, immediate. She IS what she has done.
+  Her signature: *"Your body knows. Stop asking your mind for permission."*
+
+- DORIAN'S SCHOOL (Frost-Bound Institute) — Magic as mental architecture. Power lives in disciplined
+  will and possibility-space: pre-visualization so precise that reality bends to meet the intended
+  outcome. Students don't practice spells; they build perfect internal models then execute once.
+  Dorian's power is exact, intentional, pre-planned. He IS what he intends.
+  His signature: *"You cannot build what you cannot first see, completely, in your mind."*
+
+The conflict: Mira teaches by doing; Dorian teaches by thinking. Their pedagogical philosophies are
+in irreconcilable opposition — yet both are demonstrably right, which is the problem.
+
+Deeper layer (Memory/Possibility): Mira occasionally picks up physical memories from things she
+touches (she can't always tell if it's true memory or her imagination). Dorian's pre-visualization
+sometimes collapses into fixed outcomes — he can't tell if he predicted the future or created it.
+Both characters share the same underlying question: *Is what I know real, or did I construct it?*
+
+The climax resolves the duality: both schools need the other to function fully — resolved in unified
+magic and action, never in metaphor or explicit theme statement.
