Classify installed macOS printers from their native device URI as USB, NETWORK, or unknown, instead of labeling every print queue as USB.
Classify installed macOS printers from their native device URI as USB, NETWORK, or unknown, instead of labeling every print queue as USB.

Add Printer.deviceUri, queueName, isSystemPrinter, and connectionTypeFromDeviceUri, preserving queue metadata through serialization and connection-state updates.

Include installed macOS network queues in the default scan. Explicit USB-only scans now exclude network queues; NETWORK-only scans return installed macOS network queues. Unknown queues appear when both USB and NETWORK are requested.

Keep macOS system queues on the native printing backend for connection checks, printData, and printWidget, regardless of connection type. Network classification does not imply ESC/POS compatibility or discover uninstalled LAN printers.

Refresh macOS queue snapshots to remove deleted printers and reflect changed connection types, and return filtered device-list snapshots to stream listeners.

Update the example to include network queues and display each printer's connection type, with regression tests for classification, filtering, metadata preservation, and native print routing.

Preserved BLE advertisement data (services, serviceData, and manufacturerDataList) when scan results are converted to Printer objects and during connection-state synchronization. Thanks to @Erengun for the changes in PR #50.
