feat(wechathook): 语音全合成追踪 — 定位内联 cgi uploadvoice 路 + 捕获 wire 协议 

真机 hook 追踪确认本机语音走 jg0.x.w 内联 cgi 分支（非 CDN 引擎 addSendTask，
那是 send_use_cdn_upload=1 的机器才走）。内联路可 z2.b 全合成，复用文字同队列。

新增追踪 hook:
- hookCdnTrace: h2.d(addSendTask)/l1.keep_onUpload*/jg0.x.u — 证实 CDN 路本机不触发。
- hookVoiceCgiCapture: hook modelbase.l.a() 过滤 uploadvoice，按类型定位字段（base≠
  tinker 名，NoSuchFieldError 教训），dump 请求 pb r45.cv6 全字段。

捕获的 wire 协议（cgi /cgi-bin/micromsg-bin/uploadvoice, cmdid 127, req cv6/resp dv6）:
  [0]self [1]talker [2]netOffset [3]本块SILK长 [4]"newSendVoice_"+voiceId
  [6]时长ms [7]custom cu5(SILK字节) [8]endflag [11]msgsource [12]=4 [15]long
  分块=6000字节/片，末块 end=1 响应 dv6.getLong(11)>0=服务器msgId=投递。
  scene modelbase.g extends m1 → z2.b(scene) 同文字。modelbase.o 有公开构造器可绕
  过 modelbase.l 字段名不匹配。

下一步: sendVoiceViaCgi 实现分块 cgi + z2.b 全合成。详见 memory + WECHAT_SEND_API。
