DeepSeek Harness Plugin: Local Plugin Switch (`dsh-local-plugin-switch`)

`dsh-local-plugin-switch` is a lightweight plugin for DeepSeek Harness (DSH), designed to eliminate the cumbersome process of manually editing YAML configuration files and restarting instances during local development. With visual switches on the settings page, it allows users to enable or disable local, ungrouped plugins in real time and persist their status to the configuration file. Its core capabilities include a self-contained YAML editor based on a heuristic algorithm, native/host recognition with favorites pinned to the top, and a zero-dependency architecture. Manual file mounting is required during deployment. By using HTTP routes and native slots, this tool provides developers with an efficient entry point for managing Loader state.
