Flow 0.4.14 · Resilient magnet metadata discovery

磁力元数据解析改进：兼容未在握手中给出大小的节点；跨节点、跨找源轮次保留片段，收齐后进行完整 SHA-1 校验；修复节点发完最后片段立即断线时误报失败。

增加有限并发及两片段请求窗口、失败节点退避重连，以及可取消的持续找源轮次。暂停、删除及退出会停止解析与等待。界面显示真实解析阶段、保留片段数、具体失败原因及下一次找源倒计时，中英文说明同步更新。

Metadata resolution now supports peers that omit the handshake size, collects fragments across peers and discovery rounds, and verifies the full SHA-1 before use. A peer disconnecting immediately after the final valid fragment no longer causes a false failure. Requests and memory are bounded, failed peers retry with backoff, and continuing discovery can be cancelled by pause, deletion or shutdown. The UI shows actual resolution stages, retained fragment counts, concrete errors and retry countdowns.

Validation: 61 application tests passed, including controlled cross-peer assembly, malformed sizes, hash-failure recovery, failed-peer retries and pause/shutdown cancellation; 9 installer and 2 uninstaller tests passed. Two optional player tests skipped. Packaged engine startup, metadata interoperability against libtorrent, signed update manifest, checksums and portable ZIP contents verified.

Fragment caches are memory-only within the current application session. These improvements do not create missing seeders or guarantee cold-resource availability.
