docs: redesign GitHub Pages landing page with improved navigation and UX

- Rewrite DOCS.md as compelling project landing page with:
  - Bilingual hero section with CI badges
  - Project highlights and tech stack overview
  - Example modules with expected speedup metrics
  - 6-week study plan and reading paths
- Restructure SUMMARY.md navigation:
  - Group sections by language and topic
  - Add Changelog section (6 entries)
  - Move GitBook sync guides under Contributing
- Update book.json with new plugins:
  - back-to-top-button, code copy, expandable chapters
  - Change language to zh-hans for bilingual support
- Update pages.yml sparse-checkout to include changelog
- Add HonKit plugin dependencies to package.json

+# C++ High Performance Computing Optimization Guide
 
-This site is the documentation entry for the C++ High Performance Computing Optimization Guide. Start here when you want a reading path, a language-specific guide, or direct access to the example modules.
+> **通过可运行的示例学习现代 C++ 性能工程** — 从构建系统到内存优化、SIMD 向量化、并发编程与性能分析，一站式掌握。
+>
+> Learn modern C++ performance engineering through runnable examples — covering build systems, memory & cache, SIMD, concurrency, benchmarking, and profiling.
 
-## Project Positioning
+[![CI](https://github.com/LessUp/cpp-high-performance-guide/actions/workflows/ci.yml/badge.svg)](https://github.com/LessUp/cpp-high-performance-guide/actions/workflows/ci.yml) [![Docs](https://github.com/LessUp/cpp-high-performance-guide/actions/workflows/pages.yml/badge.svg)](https://github.com/LessUp/cpp-high-performance-guide/actions/workflows/pages.yml) [![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg)](https://github.com/LessUp/cpp-high-performance-guide/blob/master/LICENSE)
 
-- Learn modern C++ performance engineering through runnable examples instead of isolated notes.
-- Cover the path from build system fundamentals to memory and cache behavior, SIMD, concurrency, benchmarking, and profiling.
-- Keep the repository README focused on repository setup while this page focuses on documentation entry points and reading order.
+---
 
-## Who This Is For
+## Why This Project / 为什么选这个项目
 
-- C++ engineers who want a structured path into performance optimization.
-- Students and self-learners comparing optimization techniques with executable examples.
-- Maintainers who need profiling, benchmarking, and contribution references.
+- **实战驱动** — 每个优化技术都有可编译、可运行、可度量的示例代码，而非孤立的知识笔记。
+- **从入门到进阶** — 6 个阶段、5 大模块，覆盖构建系统基础到无锁编程。
+- **自带基准测试** — 集成 Google Benchmark，每个模块都能量化优化前后的性能差异。
+- **工业级工程实践** — CMake Presets、Sanitizers（ASan / TSan / UBSan）、CI/CD、FlameGraph 全覆盖。
+- **双语文档** — 中英文学习路径与性能分析指南同步维护。
