旧实现里 _transferProgress 只在 transferFile() 内部才置 0，但
transferMedia 要先走 validateMediaFormat → aniConverter.convert →
prepareTransfer 这条数秒级异步链，期间 StateFlow 还停留在上次结束
的 100。集成方一 collect 就看到旧值 100，体感像「上次进度被带过来」。

修法：transferMedia 在 ensureConnected() 后立即 _transferProgress.value = 0，
collector 立即收到 0；后续 transferFile() 内的 = 0 因 StateFlow 的
distinct-value 语义被天然跳过。

对齐 ios:ed7de42。
