Chinese README polished 3 rounds:
- Round 1: direct translation
- Round 2: too dry, too many tables, too technical
- Round 3: conversational tone, scenario-driven, collapsible details
Key improvements:
- Opens with WHY not WHAT ('你的Agent很聪明，但是看不见')
- Install section explains WHERE to paste for newbies
- Features shown as bullet list not tables (better visual scan)
- Architecture hidden in collapsible section (most users don't care)
- 'Why Agent Eyes' section explains positioning clearly
- English version at docs/README_en.md
