🤖 Messages now understand real Markdown. Alongside the formatting you already
use — **bold**, *italics*, `code`, ~strikethrough~, > quotes and ``` code
blocks — you can write bulleted and numbered lists, link a word instead of
pasting a bare URL (`[like this](https://…)`), and combine formatting freely:
bold text inside a quote, a link inside bold, nested lists. Formatting is also
more predictable — a bold phrase that ends in a link now renders correctly,
and stray asterisks in ordinary text no longer italicise things by accident.
We keep it deliberately small: things like headings and tables stay plain
text in a chat.
