	ColliderSystem (rtk::collision::CollisionBuffer &collisionBuffer, float cellSize, busEvent &eventBus)
	Creates the system.

void	onStart (rtk::ecs::Registry &) override
	Logs that the system is loaded.

void	update (rtk::ecs::Registry &registry, float) override
	Rebuilds the grid and reports every overlapping pair.

void	onStop (rtk::ecs::Registry &) override
	Clears the grid and the collision buffer.

Detailed Description

Detects overlapping colliders with a uniform spatial hash grid.

Each pair is reported once per frame in the CollisionBuffer and as a rtk::collision::Collision event, if each collider mask accepts the other collider layer.
