🤖 A new Mac app (0.9.6), all about the conversation holding still.

The `/`, `@` and `:` suggestion lists now float above the message box instead
of pushing the whole conversation upwards as you type and the list of matches
narrows. A long list stops at a readable height and scrolls, rather than
covering the chat you're floating over.

Scrolling back to re-read something is steadier too: a link preview finishing
loading, someone else starting to type, or changing the text size no longer
pulls you down to the newest message. That only ever happened when the newest
message was a long one — which is exactly when you'd least want to be moved.
