Update via to v0.4.0 and decouple tick rate from snake speed

Browse Source 
Use via.OnKeyDownMap for snake keybindings, replacing the manual
dataExpr/rawDataAttr workaround. Window-scoped key handling removes
the need for tabindex/focus hacks, and WithPreventDefault on arrow
keys prevents page scrolling during gameplay.

Introduce a 60 FPS tick loop with a separate snake movement speed
(7 cells/s) so direction input is polled every frame but game state
only advances at the configured rate.
