refactor(v13): continuity auditor checks memo drift instead of volume-outline drift [phase 6/8 part 1]

Dimension 33 renamed: '大纲偏离检测' -> '章节备忘偏离' / 'Outline Drift Check' ->
'Chapter Memo Drift Check'. Auditor now receives the optional chapterMemo from
the review cycle and compares actual prose against memo goal + 7-section body
instead of cross-referencing volume_outline.md. Sparse memos (breather chapters
with goal + skeleton body only) are explicitly legal and must not be flagged as
incomplete.

- continuity.ts: drop outlineBlock in user prompt, inject memoBlock; update
  dim 33 note + label; add chapterMemo to auditChapter options.
- runner.ts + chapter-review-cycle.ts: thread ChapterMemo through the audit
  call path (including the standalone revise command).
- continuity.test.ts: swap outline-drift assertion for memo-drift assertion.

No schema fields added; all changes are prompt + plumbing.
