Class GateTransfer<T>

Transfer with state management (gate) for controlling data flow.

Capabilities: isInput, isOutput, isPushable, isSubscribable, isGate

Mechanics:

1. push(data) — writes and notifies subscribers only if active === true If the gate is closed (active === false), data is ignored
2. subscribe(handler) — subscribes to notifications
3. activate()/deactivate()/toggle() — control the gate state
4. destroy() — deactivates the gate, unsubscribes subscribers, clears state

Configuration (GateTransferConfig):

• activated: boolean — initial gate state
• initialValue?: T — initial value in _state

Use cases:

• Blocking data flow by condition (e.g., until the user is authenticated)
• Enabling/disabling event processing
• Implementing PassBridge and other bridges
