[Bug]: Browser back button not working properly when navigating from /learn to main page

Summary

Problem: When navigating from http://localhost:3000/learn to a specific learning page (like Quick Start), clicking the browser's back button does not return to the main page at http://localhost:3000/ .

Steps to Reproduce:

1. Go to http://localhost:3000/learn
2. Click on "Quick Start" (or any other learning section)
3. Click the browser's back button
4. Expected: Should return to http://localhost:3000/
5. Actual: Does not navigate back to main page

Browser: Chrome

Page

http://localhost:3000/learn

Details

Additional Context: This appears to be a navigation history issue where the browser's back button functionality is not working as expected when moving between the main page and learning sections. The issue might be related to how Next.js handles client-side routing in the learning section.

Possible Related Issues:

• Similar to the fragment link back button issue that was recently fixed
• May involve scroll restoration or navigation state management

首先，在 Chrome 中复现从 /learn 到 Quick Start 再返回主页的流程。然后检查学习部分使用 Next.js 的客户端路由，并将其与最近修复的片段链接导航进行比较。完成的标准是：浏览器的后退按钮能够按预期从学习页面返回到 http://localhost:3000/。
