/**
* Runs a long-polling showcase of the rich-message APIs introduced in Telegram Bot API 10.1 and 10.2.
*
* Outgoing [dev.inmo.tgbotapi.types.rich.InputRichMessage] values use one of three representations:
* [InputRichMessageHTML], [InputRichMessageMarkdown], or a typed [InputRichMessageBlocks] tree of
* [dev.inmo.tgbotapi.types.rich.InputRichBlock] values. The handlers demonstrate [sendRichMessage],
* [sendRichMessageDraft] revisions sharing a draft ID (including draft-only `thinking()` blocks), and edits
* through [EditChatMessageRichText]. Media is shown both as [InputRichMessageMedia] references such as
* `tg://photo?id=...` and as typed blocks; [dev.inmo.tgbotapi.requests.send.SendRichMessage] also turns
* multipart files inside an input tree into `attach://` uploads.
*
* Incoming [dev.inmo.tgbotapi.types.message.content.RichMessageContent] and user-selected content covers
* [onRichMessage], [waitRichMessage], [onlyRichMessageContentMessages], photo reuse, and
* [InputRichMessageContent] in inline and guest-query results. Parsed content is exposed as a
* [dev.inmo.tgbotapi.types.rich.RichMessage] containing [dev.inmo.tgbotapi.types.rich.RichBlock]s.
*
* @param args the bot token followed by optional, case-sensitive `debug` and `testServer` flags. The token
* must be present; unrecognized later arguments are ignored.
