根因：重写的 patch_dll_crc.py 用 binascii.crc32(data, 0xFFFFFFFF) 计算 CRC，
该参数是"末值异或之后的运行值"，再喂回去等于重复施加了条件化，得到的是
CRC32 的另一个变体，与 90CN.cpp 里 Crc32Update 的实现不一致。结果是补丁写
入的 expected 永远校验不过，客户端在 VerifySelfIntegrity 失败后安装流程中断，
transport 钩子（codec/decode/route/dproto）全部没装上，表现为"无法连接频道"。
改动：
- tools/patch_dll_crc.py
* CRC 改为标准 zlib.crc32（init 默认 0），与 C 端 Crc32Update 完全一致；
已用旧版本 DLL 反向验证（10-20、11-03、10-28 三份的存储值均能复算一致）
* 槽位改为按 PE 段表定位，只接受 .data/.rdata 内的候选，拒绝把补丁写进
.text 机器码（此前曾命中 cmp ..., 0C0DEC0DEh 的立即数导致访问违例）
* 新增 info/verify 子命令，patch 后自动回读校验
- 90CN.cpp
* SelfCrcSlot 三个字段加 volatile，避免 /O2 把 offset/expected 折叠成常量
* VerifySelfIntegrity 增加分步诊断日志，便于定位安装线程中断点
- client_build_id.go
* 指纹重绑为本次构建产物：1215488 / C7BE377C…8247071A
验证：客户端日志 self crc check computed==expected==0x80AFC116 ok=1，
transport DLL installed codec=1 decode=1 route=1 dproto=1，
channel connect result=1，first-login watchdog server_seen=1 client_seen=1。
