独立红包消息 (appmsg type=2001) 走 _format_app_message_text generic 分支, 渲染成无信息 [链接/文件], 丢场景/祝福语/发红包人. _INNER_APPMSG_TYPE_LABEL 里的 '2001':'红包' 只在引用回复嵌套路径生效. 新增 _format_redpacket_message_text, 跟已合并的 _format_transfer_message_text (#85) / _format_location_text (#124) 同款 type→结构化 inline 渲染: - [红包·<场景>] <祝福语> (发自 <wxid>) - 场景 scenetext, 祝福语 sendertitle - 发红包人从领取链接 nativeurl 的 sendusername= 参数提取 测试: tests/test_redpacket_message.py 9 case 全过.

"""测试 appmsg type=2001（微信红包）解析与渲染。
|
||
|
||
此前独立红包消息走 _format_app_message_text 的 generic 分支，渲染成无信息的
|
||
`[链接/文件]`，丢掉 scenetext（场景）/ sendertitle（祝福语）/ 发红包人。本组用例
|
||
钉住新行为：紧凑的 `[红包·<场景>] <祝福语> (发自 <wxid>)` 一行。
|
||
|
||
fixture 全部合成，无任何真实 wxid / 昵称 / 金额 / id。
|
||
|
||
金额：标准微信红包的消息 XML 不含金额字段（金额在领取后才可见，不写进消息），
|
||
仅「群收款」/「活动账单」在 <senderdes> 带人均额。由 test_*_amount 用例钉住。
|
||
|
||
发红包人：wxid 藏在领取链接 <nativeurl> 的 sendusername= 参数里。
