Per §14.10 of the plan, implemented shareable bot profile cards:
- Canvas-rendered PNG cards (800x450) with bot stats and branding
- Open Graph tags for social sharing (og:image points to /r2/cards/{bot_id}.png)
- "Share Card" button on bot profile page downloads the card as PNG
- Card displays: name, rating, rank badge, owner, archetype, win rate, stats
- Evolved badge, signature move, and recent rival info
- Responsive styles for desktop and mobile
