feat(docs): 解除 archived-components 注释并创建 scheduled-tasks 组件

- 解锁 29 个归档组件 (Project Architecture, Rate Limiting, Search Engines, File Storage, Async Task Queues, Scheduled Tasks, Computer Fundamentals)
- 修复 RateLimitAlgorithmDemo build 卡住问题 (移除末尾 reset() 调用)
- 修复 RuntimeEnvironmentDemo eval 安全警告
- 添加 Vite build chunkSizeWarningLimit 配置
- 添加 Vue 组件开发规范文档 (VUE_COMPONENT_RULES.md)
