v0.1.8

Sprite replays and leagues

• Replays got a facelift: the viewer now renders tiled ground, rock walls, seed food, and team-tinted ants that face where they're going — with a sprites toggle and the old flat style as fallback. Works in sensei replay and on the site.
• Leagues are live on the ladder: wood, bronze, and silver divisions with boss gates. Beat Genghis Ant to leave wood; beat Sun Tz-ant to reach silver. The leaderboard shows your league, and your profile shows the boss standing between you and promotion.
• Profile match history now has timestamps, filters, and boss-challenge tags.
