v1.1.0: 真实网页采集(可读正文全文入库) + 大模型接口多预置一键切换(SiliconFlow默认) + 数据源可编辑

- 新增 crawler.py: requests+bs4 readability风格清洗, 提取候选链接按文章相似度排序, 前5条抓全文存 articles.full_text, 详情页展示; example.com占位源走模拟, 真实源失败标记error不造假
- 大模型: 新增 llm_providers 表(预置 SiliconFlow/DeepSeek官方/Autodl/Local Qwen), 设置页增删改/测试/一键切换, 激活接口失败自动切换备用
- 数据源: 前端补编辑按钮+弹窗(后端 update 已支持), 列表显示URL与采集状态
- 数据库迁移: articles.full_text 列 + llm_providers 表
