feat(wechathook): 语音全合成打通 ✅ — uploadvoice cgi 服务器接受(errCode=0+svrMsgId) 

修好派发：裸 z2.b(g) 不 wire 回调 → 场景永不完成、dv6 空。正确派发 =
modelbase.i.l()（注册响应消费者 d + 返回 pq5.g deferred）+ pq5.g.l(timeoutMs)
终端订阅触发 cgi。加 sVoiceCgiKeepAlive 强引用防 deferred 弱持有的 i 被 GC。

真机 filehelper 验证（纯合成，无录音/无 hot-swap）:
  RESP try=1 svrMsgId(11)=6727180359918674774
  VOICECGI-RESULT errType=0 errCode=0 errMsg=null respClass=r45.dv6
= 服务器接受请求(errCode=0) + 分配 msgId(>0) = 投递成功。

诊断 hook hookVoiceCgiResult(modelbase.i onSceneEnd 按签名定位) 确认 errCode。
广播 SEND_VOICE_CGI --es to --es src_path <SILK> --ei duration。SILK 须 WeChat
进程可读（用其自身 voice2 文件或 chown 到 WeChat uid；/sdcard 会 EACCES）。
