This commit adds a new AppIntent called TracerouteIntent, allowing users to send a traceroute request to a specific Meshtastic node directly via iOS Shortcuts or Siri.
The intent calls BLEManager.shared.sendTraceRouteRequest(destNum:wantResponse:) and provides basic validation to ensure the device is connected.
No other files or logic were modified. This follows the same structural pattern as MessageNodeIntent.swift.
