dsh-route-fence-linter: A Static Security Check Tool for HTTP Routing in DeepSeek Harness Plugins

This tool statically scans the HTTP routing security of DeepSeek Harness (DSH) plugins to ensure that browser trust fences are correctly implemented to defend against attacks such as DNS rebinding. Core features include checking Host pinning, fallback registration, and reference resolution. It supports scanning a specific path via CLI and outputs PASS, WARN, or FAIL result levels. Based on heuristic analysis, it scans only package release files and is intended for DSH plugin developers to perform security checks.
