feat: 早报系统重构与功能增强

- 新增常驻调度器 daily/scheduler.py + run-scheduler.ps1（定时生成/推送）
- 新增 daily/bridge_manager.py：Windows 兼容的 Cursor SDK 桥接
- 新增 skills/daily-featured-pick 首推 Skill 与叙事轴/去重逻辑
- 新闻抓取窗口、GitHub 搜索、企微 delta 模式等多项改进
- 补充设计文档与 superpowers 计划/规范
- 新增对应测试（scheduler、featured_pick、github_search、news_fetch_window 等）
