Sprint 56h: butterfly effect + character sheet auto-import

- drafting.yml: add {character_profiles} in PASS 0, PASS 3 character state
  extraction, rag_write for character-state asset (enables butterfly effect
  in draft mode), document for character-state file, conditional_skills
- character_sheet.yml: add rag_write step writing voice-sig-{slug} asset
  so auto-import can pick up completed character sheets from RagMemory
- book_chapter.yml: package hint now detects new characters from PASS 3
  Character State (spawns character_sheet tasks) and detects Permanent:YES
  changes (spawns character_update tasks)

+      NEW CHARACTER DETECTION (Bug G fix):
+      Look at the Character State from PASS 3 above (step 4). For each character listed there
+      whose name slug does NOT already have a "character-{slug}" file in PROJECT DELIVERABLES,
+      emit one additional create_task action per new character using task_type: character_sheet.
+      This ensures new characters introduced in this chapter get proper character sheets.
+
+      PERMANENT CHANGE DETECTION (butterfly effect):
+      For any character in the Character State whose "Permanent:" field is YES,
+      emit one additional create_task action using task_type: character_update.
+      This triggers the character update pipeline to record deaths, power changes, etc.
