mkaliezz/dsh-agent-doctor: DeepSeek Harness Tool-Side Diagnostic Plugin

`dsh-agent-doctor` is a lightweight security diagnostic plugin for DeepSeek Harness (DSH). It performs a static audit of an Agent's tool surface via the `/doctor` command, checking the tool inventory, reserved interface visibility (e.g., `run_code`), heuristic warnings, and AgentFuse status. The plugin helps developers audit configurations to prevent accidental exposure of code execution interfaces that should not be accessible, but it is not an antivirus or sandbox and cannot replace enforcement of security policies.
