close

Closes the GATT connection and releases all associated resources.

This method performs a complete cleanup:

• Cancels any pending reconnection attempts.

• Cancels all pending operation timeouts.

• Closes the BluetoothGatt instance.

• Transitions to ConnectionState.Disconnected.

Unlike disconnect, this method does NOT trigger auto-reconnection, making it suitable for permanent disconnection scenarios.

After calling this method, you must call connect again to re-establish a connection. The bluetoothGatt property will be null after this call.
