feat(wechathook): 语音全合成 sendVoiceViaCgi — uploadvoice cgi + z2.b（提交跑通） 

按捕获的 wire 协议实现全合成语音（无录音、无 hot-swap）:
- 读 SILK → 按 6000 字节分块 → 每块建 r45.cv6 请求 pb（[0]self [1]talker
  [2]offset [3]len [4]"newSendVoice_"+voiceId [6]dur [7]cu5(SILK切片) [8]end
  [11]msgsource [12]=4）→ 经 modelbase.o 13参构造器(绕过 modelbase.l 字段名
  base≠tinker 不匹配) → modelbase.i.p(o)(按签名定位) → scene modelbase.g(m1)
  → z2.b(scene) 入队（同文字发送）。
- 广播 SEND_VOICE_CGI --es to --es src_path <SILK> --ei duration。

真机 filehelper 测试：反射全部解析成功，scene=com.tencent.mm.modelbase.g，
z2.b 提交 1 块无异常（silk=2593B dur=2000）。投递确认待（设备屏幕 doze +
需第二账号）；已知待补：[15] long 字段省略、本地 f9 气泡未插、cgi 响应
getLong(11) 未校。
