LanLens v1.4.5 — Multi-subnet discovery

New Features

• Added optional routed scan targets in Settings → Network Discovery.
• Additional IPv4 CIDRs/addresses are discovered with nmap -sn -n, enabling host discovery beyond the directly connected Layer-2 LAN.
• Added stable IP-only tracking for routed hosts where MAC/vendor data is unavailable.
• Added duplicate protection when routed targets overlap with local ARP discovery or when IP-only devices later become discoverable with a real MAC.

Improvements

• Routed nmap discovery runs as one bounded multi-target invocation instead of one subprocess per target.
• Additional routed scan targets are validated and limited to avoid accidental huge scans.
• Settings store additional scan targets one per line.
• IP-only host labels are localized in the UI and aligned with notifications.

Documentation / Responsible Use

• Documented local ARP discovery versus routed subnet discovery, including MAC/vendor limitations across routed networks.
• Added a responsible-use notice: LanLens must only be used in your own network or in networks where you have explicit permission. Network discovery and port scanning can be misused; users are responsible for lawful and authorized use.
