按 msext gameController.m:637-678 字面行为，WechatShare 按 content.type 分发： - type=1 → shareLink（已有） - type=2 → captureScreenshot → JPEG 0.6 + thumb 0.4x → shareImage - type=其它 → downloadRemote(URL) → JPEG 0.9 + thumb 0.4x → shareImage 新增： - ImageProvider.scaledThumb(_:scale:)：等价 msext FuncPublic imageByScalingAndCroppingForSize 0.4x 缩放；微信 SDK setThumbImage: 内部再压到 32KB - WeChatManager.ShareImage 结构 + shareImage(_:scene:) 异步包装 （WXImageObject + WXMediaMessage.setThumbImage，FIFO 串行复用 sharePending） 契约：与 type=1 一致，调成功 → sharesuccess 反向 callback（success/cancelled 都发）；errCode=-2 → cancelled；其它 errCode → failed。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
