feat(share): ShareProvider 去SDK化三段式分享 + WeChatApi 仅留登录（分享重构 §4/§5/§7）

- WeChatApi：移除 SendMessageToWXResp/SendMessageToWXReq/WXMediaMessage/WXWebpageObject/WXImageObject/ErrCode/shareCb/sendShare；仅保留登录路径（sendAuth/handleWant/SendAuthResp）
- ShareProvider：完全去 wechat_open_sdk 分享依赖，改「剪贴板+ShareGuideDialog→系统分享」三段式架构；保留 FriendsShare 注册、PHOTO_UPLOAD 链路、captureCanvas 截图、systemShare 兜底、乐观回传 sharesuccess；新增 type3 图片链接下载路径

- * 分享能力（契约 §8.1/§10.1，T-M3-13）。对齐原 Android「自定义三按钮分享面板」（微信/QQ/抖音）。
+ * 分享能力（契约 §8.1/§10.1）。三端统一「剪贴板+指引窗 → 系统分享」，**不依赖任何分享 SDK**。
  *
- *  H5 调 friendsSharetypeUrlToptitleDescript（data=sharetypeBean JSON）→ 弹自定义面板（entry 容器渲染）。
- *  用户点平台后经一次性 resultEvent 回投本 Provider：
- *   - 微信（@tencent/wechat_open_sdk）：
- *       type=="2" → Canvas 截图图片分享（截当前激活 Web 的 canvas.toDataURL → 落盘 → WXImageObject.uri）；
- *       其他 type → 网页分享（WXWebpageObject）。
- *       scene：sharefriend=="1" → 好友(WXSceneSession)，否则 → 朋友圈(WXSceneTimeline)。
- *       分享结果回传 H5：callHandler('sharesuccess', {success:2成功/3取消, type:1好友/2朋友圈})。
- *   - QQ / 抖音（不集成对应 SDK，用 HarmonyOS 系统分享 @kit.ShareKit，让用户在系统面板选目标 app）：
- *       type=="1" → 文本(title+description)；type=="2" → 截图图片；
- *       type=="4"(抖音视频) → 视频(webpageUrl 为视频地址)；else → 网页链接(webpageUrl)。**不回传 sharesuccess**。
+ *  H5 调 friendsSharetypeUrlToptitleDescript(data=sharetypeBean JSON)：
+ *   - sharefriend=="2" → 直接微信指引窗（朋友圈语义，回传 type=2）。
+ *   - sharefriend=="1" → 弹自定义面板(微信/QQ/抖音/取消) → 选定渠道。
+ *  选定渠道后按内容类型组装并写剪贴板，再弹 ShareGuideDialog：
+ *   - 文本(type1/4/其他)：剪贴板 PLAIN_TEXT(title\ndescription，无 url)；
+ *   - 图片(type2 截图 / type3 图片链接下载，低优先)：剪贴板 PIXELMAP(尽力)。
+ *  指引窗动作：打开App(openLink scheme，best-effort) / 用系统分享(systemText|systemImage，可靠) / 取消。
+ *  仅微信乐观回传 sharesuccess：打开/系统分享→{success:2,type}；取消→{success:3,type}。QQ/抖音不回传。
  *
- * ⚠ 微信运行期成功需在微信开放平台注册本 HarmonyOS 应用（bundleName+指纹 绑定 AppID）。
- * 截图/系统分享拉起/微信分享 均只能真机验证。
+ * 注：图片"复制剪贴板再去对方App粘贴"能否成功取决于对方是否读 PIXELMAP（鸿蒙不可保证），
+ * 故指引窗"用系统分享"(systemImage) 为可靠兜底；拉起 App 仅打开、不预填（需用户自行粘贴）。
