feat(renderer): polish gameplay visuals — transport, starfield, sparkles, smooth piece motion

Browse Source 
Add transport/transfer effect for NEXT → grid with cross-fade and preview swap
Integrate in-grid Starfield3D with magnet targeting tied to active piece
Spawn ambient sparkles and impact sparks (hard-drop crackle + burst on expiry)
Smooth horizontal/fall interpolation for active piece (configurable smooth scroll)
Refactor next panel / preview rendering and connector drawing
Tweak stats/score panel layout, progress bars and typography for compact view
Preserve safe alpha handling and restore renderer blend/scale state after overlays
