P1: 功能修复
- v2 三处 self.format_file_size -> format_file_size(3 个端点不再必崩) - requirements 加 bcrypt、移除未使用的 aiohttp - verify_user 改用 bcrypt.checkpw(DB basic 登录恢复);SHA256 回退改自描述 PBKDF2,去掉明文接受 - config.py token 模式只在缺失时生成(不再每次 update 失效) - docker/npm/go/apt/yum 镜像补 cache_enabled/cache_ttl 初始化(不再必 500) - docker 镜像兼容 upstream_url 配置键 - 定时同步链路: 回调委托 sync_starter 并注入 _sync_manager;cron 逗号列表修复;星期偏移修复 - v2 同步方法与 v1 签名兼容;MirrorSyncManager 补 get_source_status/stop_all_tasks_for_source
