- 新增 /api/sns/users：按发圈数统计联系人（支持 keyword/limit） - 新增 /api/sns/realtime/sync_latest：WCDB 实时增量同步到解密库（append-only），并持久化 sync state - 朋友圈媒体优先走“远程下载+解密”：图片支持 wcdb_decrypt_sns_image，视频/实况支持 ISAAC64（WeFlow 逻辑） - 增加 WeFlow WASM keystream(Node) 优先 + Python ISAAC64 fallback，提升兼容性 - wcdb_api.dll 支持多路径自动发现/环境变量覆盖，并在状态信息中回传实际使用路径
