DeepSeek Harness web plugin that adds a LAN access

Key features

• The /api trust fence is updated live, so the browser on a LAN machine works fully (chat, tools, workspace).
• Enabling shows the ONE address other devices can open — the IPv4 of the interface that owns the default route ( — with a copy button.
• The /api gateway pins the configuration plane (settings., credentials.) to loopback.
• The DSH launcher itself refuses --host 0.0.0.0 for the same reason: binding all interfaces exposes the agent's tools to the network.
• Off — the GUI binds 127.0.0.1 again (loopback only — the safe default).
