Sprint 2: gameplay — achievements, score popups, new enemy, polish

- AchievementsManager with 10 unlockables and toast popups
  (Genesis Block, Chain Reaction x3, Bug Hunter, First Flight,
   Liftoff, Power Trip, Survivor 500, Skyscraper 1000,
   Speedrun 100/60s, Gas Baron 50k)
- Score popups: +N text floats above player on every landing
  (gold and larger for genesis platforms)
- Powerup duration bar in HUD bottom, color-coded per power-up,
  uses scaleX for smooth depletion animation
- New enemy: Failed Tx, falls from above with sine drift, unlocks
  at difficulty > 800, can be stomped, tinted red
- Dynamic background: dark cosmic overlay alpha scales with height
  (max 0.5 at very high altitudes)
- Achievement hooks integrated into ScoreManager, GameScene
- Combo no longer resets if combo was already 0 (was triggering log spam)
