docs: add simplified Chinese (zh-CN) README translation

[howardpen9]

Summary

• Add README.zh-CN.md — full simplified Chinese translation of the project README
• Add language switcher (English | 简体中文) to the original README.md header

All section headings, feature descriptions, architecture diagrams, installation instructions, and configuration guides are translated. Code blocks and command examples are preserved as-is.

Test plan

• Verify README.zh-CN.md renders correctly on GitHub
• Verify language switcher links work in both README files
• Verify all internal anchor links (#设计理念, #功能特性, etc.) navigate correctly

Code Review

This pull request adds a Simplified Chinese translation of the README, which is a valuable addition for international users. My review of the new README.zh-CN.md file identified a broken link and an opportunity to improve navigation by completing the table of contents. The proposed changes will fix these minor issues.

_{Note: Security Review has been skipped due to the limited scope of the PR.}

[gemini-code-assist]

The link for the license badge points to #license, but the corresponding section header in this file is ## 许可证. This results in a broken link. To fix this, the href should be updated to #许可证 to match the anchor generated for the Chinese header.

Suggested change

	<a href="#license"><img src="https://img.shields.io/badge/license-MIT%20OR%20Apache%202.0-blue.svg" alt="License: MIT OR Apache-2.0" /></a>
	<a href="#许可证"><img src="https://img.shields.io/badge/license-MIT%20OR%20Apache%202.0-blue.svg" alt="License: MIT OR Apache-2.0" /></a>

[gemini-code-assist]

The table of contents is incomplete and misses links to several sections like "Usage" (使用方式), "Development" (开发), "OpenClaw Heritage" (OpenClaw 传承), and "License" (许可证). Adding these will improve the document's navigation.

Note that for a header like ## OpenClaw 传承, GitHub generates the anchor #openclaw-传承.

Translation looks comprehensive and accurate. The Chinese README covers all major sections from the English version. Language switcher added to both files.

One thing to verify: make sure the translation stays in sync with future README changes. Consider adding a comment at the top of README.zh-CN.md noting which English README commit it was translated from, so contributors know when it needs updating.

LGTM.
