Add bilingual organization README as architecture index for 8 repositories

[Copilot]

The .github repository lacked documentation. Created organization-level README serving as a high-level index and architecture showcase with full bilingual support (English and Chinese).

Content Structure

• Bilingual Documentation: Complete README in both English and Chinese (中文) with language navigation links
• Repository Portfolio: Categorized 8 repos across core proxy infrastructure (sing-box modules, config templates, CI pipeline), package distribution (Arch Linux pacman repo), and network optimization (FCM hosts projects)
• Architecture Diagram: ASCII visualization showing component relationships and CDN distribution flow
• Organization Overview: Focused on describing what the organization does and how projects interconnect
• Metadata: Technologies, statistics, contributing guidelines, acknowledgments - all provided in English and Chinese

Key Details

• All repositories documented with badges, feature highlights, and homepage links
• HTTPS enforced for all external links
• 388 lines providing clear organization index and architecture showcase
• Easy language switching via anchor links at the top of the document
• Consistent structure maintained across both language versions
• No detailed usage instructions - users are directed to individual repository READMEs for specific usage guides
• Serves as a clean index page showcasing the infrastructure ecosystem

Design Philosophy

The README focuses on being an organizational index rather than a usage manual. Detailed installation and configuration instructions are intentionally omitted and deferred to individual repository documentation, keeping the main page focused on the big picture of what the organization does and how components connect together.

已完成！README.md 现在包含完整的中英双语版本。您可以通过页面顶部的链接在两种语言之间切换。所有内容（包括仓库介绍、快速开始指南、架构图等）都提供了中英文双语版本。

Done! The README.md now includes complete bilingual (English/Chinese) versions. You can switch between languages using the links at the top. All content (repository descriptions, quick start guides, architecture diagrams, etc.) is provided in both languages.

安卓用法写错了，没有sbc edit功能，主页无需描述使用方法，只需要描述这个组织是做什么用的就行，具体细节在里面，主页仅仅是个索引，展示我的整个架构的

已修改！移除了所有详细使用说明（包括错误的 sbc edit 命令）。README 现在只作为组织的索引页面，展示架构和各仓库简介，具体使用方法请查看各仓库的 README。

Fixed! Removed all detailed usage instructions (including the incorrect sbc edit command). The README now serves only as an index page showcasing the architecture and repository overview. Detailed usage guides are available in individual repository READMEs.
