InputDispatcher class Input

Central dispatcher for input events.

The InputDispatcher manages a list of InputHandlers and forwards input events to them sequentially until one handles the event.

It coordinates with RenderManager to mark components dirty and request redraws when necessary, based on the handlers' responses.

Responsibilities:

• Register and unregister input handlers.
• Dispatch input events to handlers in order.
• Manage render invalidation for updated components.
• Return true if any handler signals an exit command.

Lifecycle:

• Created with a RenderManager instance.
• Handlers can be added or removed dynamically.
• Should be used as the single entry point for input events.
