Faster Pacing, Bigger Glue Rewards & Bug Fixes / hotfixex

- Faster difficulty progression, adjusted for each mode’s board size.
- Score bonuses now grow more substantively with the proportion of glued cells cleared, with an extra 25% bonus for fully glued clears.
- Fixed several premature game-over cases involving garbage, oversized rotations, and large glued pieces that slipped through in the last version. Sorry about this!
- Improved online input responsiveness and reduced unnecessary rendering work to combat lag.
- Added an optional subtle glow to make glued blocks easier to recognize.
- Removed the two achievements tied to the unavailable Battle Royale mode.
