* Fix zero-argument MCP tool schema missing 'properties' key (#4540) MCP servers for zero-argument tools (e.g. matlab-mcp-core-server's detect_matlab_toolboxes) declare inputSchema as {"type": "object"} without a "properties" key. OpenAI's API requires "properties" to be present on object schemas, causing a 400 invalid_request_error. Normalize inputSchema at MCP ingestion in load_tools() to inject an empty "properties": {} when it is missing from object-type schemas.
