Add 3GPP Protocol Index to DeepSeek Harness with comm-protocol-hub

comm-protocol-hub is a DSH community plugin (MIT) maintained by Thanksgiver233. It has compiled 70 summaries of 3GPP protocols from Rel-15 to Rel-18 into a local knowledge base categorized into 8 types including TN/NTN, holography, near/far field, hybrid, security and etc., which can be queried through three tools: search, browsing and detail viewing. The data is embedded, and there is a panel on the Web side. This article checks the installation commands and boundaries against the catalog page and GitHub: it is a summary index rather than the full specification, and you should check the source code and license before installation.
