DeepWiki catalog entry uses deprecated SSE endpoint returning HTTP 410 #4735

The current Docker registry entry declares DeepWiki with the deprecated SSE endpoint https://mcp.deepwiki.com/sse and SSE transport.

On 2026-08-14, that public endpoint returned HTTP 410. DeepWiki's publisher documentation documents the replacement:

• URL: https://mcp.deepwiki.com/mcp
• transport: Streamable HTTP

I verified the replacement with an MCP 2025-03-26 initialize/list exchange. It advertised exactly these three tools:

• read_wiki_structure
• read_wiki_contents
• ask_question

Please update the DeepWiki catalog entry from /sse + SSE to /mcp + Streamable HTTP.

Related: #4568 noted a transport mismatch for the existing DeepWiki entry; this issue supplies the replacement endpoint and a successful protocol-level verification.
