dsh-wsl-expose: Exposing WSL Ports to the Local Network

`dsh-wsl-expose` is a DeepSeek Harness (DSH) plugin designed to enable LAN devices to access services running in WSL. It manages Windows port proxying and, based on the network mode configured in `.wslconfig`, automatically suggests or applies port forwarding rules to provide reliable connectivity. The plugin features a whitelist mechanism, network-mode awareness, and automatic port proxy application. Installation requires running the specified command, and usage must comply with security restrictions, including limiting access to the LAN, using kit relay for the local UI, and prohibiting binding to 0.0.0.0.
