feat: ludo — super juicy animations, mini dice on each player panel

- Add mini dice to all player panels showing roll result with pop-in animation
- Bot/opponent dice rolls visible next to their name with same shake + land effect
- Panel glows on six, active player has pulse + avatar bounce animation
- Pawn movement uses full arc-bounce (up→peak→down→squash) per hop
- Enter animation: pop-out from home with bounce + landing dust burst
- Long moves (3+ steps) produce particle burst on landing
- Mini dice fades out after 1.2s when turn passes to next player
- Rolling state shows rotation shake animation on mini dice
