docs(i18n): move Chinese README to docs/zh-CN/ so it renders as dir README

GitHub only renders README.md as a homepage once per directory. A second
README at repo root (README.zh-CN.md) opens in blob view with full file
chrome, which reads like source inspection rather than a landing page.

Moving to docs/zh-CN/README.md means the link [简体中文](docs/zh-CN/)
lands on a tree view that auto-renders that directory's README — same
pattern used by Vue, React Native, TypeScript, and similar multilingual
OSS projects.

- Move README.zh-CN.md -> docs/zh-CN/README.md
- Fix relative paths inside (banner.svg, demo.gif, GUIDE, INSTALL, LICENSE)
- Update EN README language switcher: README.zh-CN.md -> docs/zh-CN/
