feat(v10): P2 — reviser craft rules + architect emotional wave design

Reviser (auto mode):
- Added 3 compact craft rules to both EN/ZH revision principles:
  emotion through action, character voice differentiation, escalation

Architect (volume outline generation):
- EN: Golden 5 chapters rule (paywall at ch6-8) + emotional wave design
- ZH: Added emotional wave design (tension curves, no 3+ consecutive
  same-mood chapters, daily chapters must serve mainline)

All 520 tests pass.
