feat(channels): 适配器入站内联附件字节(telegram/kook/qq_obv11/weixin_ilink)
CI / Backend (build / vet / test / cross-compile) (push) Has been cancelled
CI / Frontend (tsc + vite build) (push) Has been cancelled

- 新增 internal/channel/mediafetch:来源白名单(deny-by-default,支持 *.suffix)
  + 逐跳重定向校验 + 边读边限 + 超时;只回来源主机,绝不回完整 URL
- 四渠道各自 media.go 接通入站内联:只从平台载荷给出的引用取回字节
  (telegram file_id→getFile→file_path 形态校验;kook CDN;qq 文件段 url;
   weixin cdnURL + AES-ECB 解密)
- 常量全部复用既有来源:documents.ExtAllowed / DefaultMaxBytes / MaxPerMessage
- channelbridge 诚实提示文案改为对「渠道只给远程引用」与「代取失败」两种成因都成立
- 18 个测试函数(含四渠道「正文里的 URL ⇒ 0 次命中」红线反证、端到端进模型可见视图)
- 变异验证:去掉尺寸上限 ⇒ 四渠道红(含修正后不再是假绿的 weixin 超量用例)
