Spring AI @JsonUnwrapped-like annotation for @McpTool parameters

Expected Behavior

It would be nice to be able to define a dedicated type for a MCP tool's parameter parameter and use a @JsonUnwrapped-like annotation on it so that it's included directly in the request.

Current Behavior

I have to manually repeat the @McpToolParam annotation each time I use the shared parameter.

Context

I have several MCP parameters that have meaningful descriptions and are used in many tools. Unfortunately, I have to manually repeat the @McpToolParam annotation each time. It would be nice to be able to define a dedicated type for this parameter and use a @JsonUnwrapped-like annotation on it so that it's included directly in the request.
