Bot users now render with a cool-toned (blue/cyan/violet/teal/indigo)
marble variant so they're visually distinguishable from human users.
Marble's rendering logic is parameterized with a palette; the route
forces the bot palette whenever the resolved user is a bot, overriding
whatever avatar provider they'd otherwise inherit.
Email notifications now display user mentions with inline avatar images for improved visual recognition and easier identification. Mentions gracefully fall back to display names if avatars are unavailable.
