dsh-env-profile: Automatically Detect Environment and Inject System Prompt

dsh-env-profile is a global memory plugin for DeepSeek Harness, designed to address the token consumption and workflow slowdown caused by repeatedly confirming local environment details (tools, paths, and network) in every new session. It automatically detects the local environment, consolidates the results into a global profile, and injects a low-overhead summary into the system prompt to achieve “instant readiness.” The plugin supports on-demand tool queries and leverages prefix caching to further reduce token costs. It is currently in the v0.1 stage and only supports Windows.
