Subject: [PATCH] feat(aiocqhttp): handle json type messages in message
 converter

Add support for parsing OneBot JSON message segments (QQ mini-program,
Bilibili share cards, etc.) in the target2yiri converter. Parses the
card metadata and converts it to plain text to avoid silently dropping
these message types.
