小助手内嵌 GM 页：网页重定向 + 物品分页 + 装备强化增幅发放
- 90CN.dll 新增 IE 控件接管，把腾讯小助手页面重定向到本地 GM 页 - gmweb：物品列表改分页（每页 10/20/50，列表固定 6 行高） - 发放走 grant-options，支持强化 0-31、增幅属性+等级、锻造 0-8、品质 - 服务端补齐 amplify_level：等级统一写入 ext_data0/packed_flag_byte/reinforce/upgrade_level - 增幅与强化互斥校验，避免写出客户端无法创建的装备

// ============================================================================
|
||||
// 90CN_web_redirect.cpp -- 把客户端内嵌网页窗口跳到本地 GM 页面
|
||||
//
|
||||
// 背景：DNF 客户端里那个「小井盖 / 小助手」窗口是 IE 内核（窗口类链为
|
||||
// Browser Example -> Shell DocObject View -> Internet Explorer_Server），
|
||||
// 地址在运行时拼接，客户端二进制与 PVF 里都没有明文域名，硬改字符串
|
||||
// 不可行。所以这里不碰原地址，而是等控件创建出来后，直接把文档导航
|
||||
// 到我们自己的页面。
|
||||
//
|
||||
// 做法：起一个后台线程轮询本进程内的 Internet Explorer_Server 窗口；一旦
|
||||
// 发现新窗口，等原生导航落定，再用 WM_HTML_GETOBJECT + ObjectFromLresult
|
||||
// 取到 IHTMLDocument2，经 IHTMLWindow2::execScript 执行
|
||||
// location.replace(...) 完成跳转。同一窗口只跳一次（force=1 时若发现
|
||||
// 文档又跑到别的域名，会再次拉回）。
|
||||
//
|
||||
// 配置：DLL 同目录的 90CN_web.ini
|
||||
// [web]
|
||||
// enabled=1
|
||||
// url=http://127.0.0.1:18112/
|
||||
// force=0
|
||||
// delay=1200
|
||||
// 没有配置文件时用上面的默认值（enabled=1）。
|
||||
//
|
||||
// 失败不影响游戏：任何一步取不到对象都只写日志，不会终止进程。
