fix(frontend): build + remove hover tooltips in step links

- Fix Turbopack build: replace raw-loader .md import with inlined about-content.ts; drop raw-loader from next.config and package.json
- Remove all hover tooltips on step-area links (web_fetch, read_file, ls, bash, write_file, web_search) so hidden steps no longer show popups

修复：构建错误与步骤链接悬停提示
- 修复 Turbopack 构建：用内联 about-content.ts 替代 raw-loader 导入 about.md，并移除 next.config 与 package.json 中的 raw-loader
- 移除步骤区域内所有链接的悬停提示（查看网页、读文件、列目录、bash、写文件、网页搜索），隐藏步骤悬停不再弹出内容
