What:
- add zh-CN versions of landing revamp pages (features, quickstart, docs directory, network model, credits)
- refresh zh-CN index and hubs, plus glossary entries

Why:
- keep Chinese docs aligned with the new English landing experience
- ensure navigation surfaces the new entry points

Tests:
