refactor(phase1.4): clean up debug logging and finalize score calculation

- Remove all console.log debug statements
- Score calculation now working correctly:
  * Each food worth current level points
  * Level up happens AFTER food is eaten and scored
  * Example: food1(+1)=1pt, food2(+1, lvlup)=2pts, food3(+2)=4pts
- FOODS_PER_LEVEL = 2 (final production setting)
- Code is clean and production-ready
