refactor(architecture): 修复模块依赖违规并强化架构守护

- 字幕编排上移 DownloadChain.download_site_subtitles，SubtitleModule 仅保留站点链接解析
- TransferChain.recommend_name 上移 TV episodes_info 获取，filemanager 模块不再导入 TmdbChain
- endpoint 穿透修复：WXBizMsgCrypt3 迁至 adapters/external/wechat_crypt.py；
  music/tmdb 缓存管理、listenbrainz 常量、TMDbException、WechatClawBot 辅助统一经 chain 包装
- RuleParser 与 builtin_rules 合并为 application/filter_rules.py；
  fsproxy/fsworker 迁至 adapters/system/
- chain/__init__.py 删除 qbittorrentapi/transmission_rpc 导入，消除后端协议类型泄漏
- 架构守护测试新增三项检查：模块间隔离、入口层穿透、下载器 SDK 泄漏
- 文档同步：05-architecture.md 记录 DB/Oper 聚合例外与迁移文件位置，AGENTS.md 更新所有权表
