Subject: [PATCH] feat: integrate via v0.18.1 context suspension and key
 throttling

Upgrade via to v0.18.1 and configure context suspension timeouts
(5min suspend, 30min TTL) for clean reconnection behavior. Throttle
snake direction key inputs to 100ms to prevent wasted SSE round-trips
when keys are held down.
