* Consistency with gekko_create

* redo disconnection logic. only fully drop when the remote is genuinely quiet.

* progress. have to make  a new func to fetch received remote inputs to the frontend tho. cuz now its stalling.

* cleanup old-back to front bridge.

* dont forget to jump by input size.

* back to front api

* CULPRIT FOUND

* this should take care of the mem leak.

* allow input bufffers to store multiple incorrectly marked frames and also clear them when solved

* ok the main cause seem to be a missed case in the input prediction logic. added this case now.
the case was that when i had already predicted the input before i was trying to predict beyond my limit rather then using the input that was already generated.

* cleanup

* fixed incorrect received input parsing

* should be spectators covered.

* spectators send inputs in parralel nor series

* ball respawn and bounce based on paddle section

* update game
