Sprint 56: Upstream draft control and editorial boundary refactor

- book_chapter: Remove PASS 2+3 (internal polish cycle); replace with narrow
  SELF-CHECK step (structural validation only — names/POV/hook/format/word-floor).
  Add anti-overpolish drafting discipline rules to PASS 1.
  Add genre-aware guide-use note (apply only the guide matching {genre_name}).
  Update adjudication prose_quality description to match draft-quality standard.

- chapter_polish: Convert from broad 'Rewrite the chapter' pass to bounded
  editorial control pass. Explicitly forbids expansion, sensory addition,
  global voice upgrades, new content. Instructs verbatim preservation of
  unaffected paragraphs. Adjudication rewritten around correction fidelity
  rather than 'more polished is better'. Threshold lowered from 90 to 80.

- chapter_review: Add explicit output categories — STRENGTHS TO PRESERVE,
  MUST-FIX CONTINUITY, MUST-FIX CLARITY, OPTIONAL, FORBIDDEN, VERDICT.
  Remove 'REWRITE' verdict option (roundtable resolves that). Remove all three
  writing-craft guides (editorial tasks do not need genre writing guidance).

- chapter_roundtable: Update CONSENSUS REACHED block to MUST APPLY / OPTIONAL /
  PRESERVE / VERDICT categories. Require disagreements to be resolved before
  calling consensus. Remove REWRITE verdict option. Remove all writing-craft
  guides. Remove 'skills' from sections. Add package hint to populate key_changes
  from the full structured consensus. Update adjudication to score structured output.

- book_outline: Strengthen Voice & Tone Guide as hard operating constraints
  (not aspirations); include anti-overpolish rules, rhythm rules, and voice
  don'ts. Expand per-chapter outline format to include Opens-at location,
  Character state, and Dominant tension. Enrich chapter task description
  packets with that state data so book_chapter has richer upstream context.

- skills/skills.md: Document writing-vs-editorial guide split established in
  Sprint 56. Update Used-by column. Add boundary rules section.

+      output the final chapter.

+
+      CHECKLIST — check each item, note any issue found:
+        1. BEAT & HOOK: Does the chapter reach its intended emotional beat and closing hook
+           from the PASS 0 draft prompt? Flag if the chapter ends without the planned hook.
+        2. NAMES & POV: Are all character names and the POV consistent with the bible/outline?
+           Flag any name that doesn't match the project canon.
+        3. CONTINUITY TERMS: Do world rules, place names, and timeline references match
+           project state? Flag any factual break.
+        4. FORMATTING: Are there obvious section-break artifacts, duplicate headers,
+           or missing chapter title? Flag and fix.
+        5. WORD FLOOR: Is the draft within 10% of {chapter_target_words}? Flag only if
+           critically short (more than 20% under target) — do not expand for style.
+
+      ALLOWED CORRECTIONS:
+        - Fix a wrong character name to match the canon name
+        - Fix a POV slip (e.g., the chapter is 1st-person but one paragraph shifted to 3rd)
+        - Fix a missing or duplicated chapter title/header
+        - If the chapter is missing its closing hook entirely, add it as a final paragraph
