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.
