dsh-port-inspector: DSH Web Port Origin Tracing and Secure Handling Tool

`dsh-port-inspector` is a port management plugin for the DeepSeek Harness Web environment, primarily addressing unclear port ownership and the risk of unintended process termination during multi-service debugging. It supports Windows and provides features such as a port overview, source identification (distinguishing DSH sessions from external processes), safe stopping, Compose detection, and quick filtering. Through identity verification, users can safely manage controlled processes or terminate clearly identified external processes, avoiding port conflicts and residual zombie processes.
