fix: use standard MCP config key "url" instead of "httpUrl"

Align with the MCP specification (and Claude Desktop) which uses "url"
for streamable HTTP server configuration. The non-standard "httpUrl" key
caused servers configured with "url" to be incorrectly treated as stdio,
leading to startup failures.
