McpAsyncRequestContext not excluded from Json schema with @McpPrompt

[mdangl]

According to the documentation, McpAsyncRequestContext should be supported for @McpPrompt.
But when we add a parameter of type McpAsyncRequestContext to a method annotated with @McpPrompt, it is turned into a prompt argument.

Might this be caused by this code, which does not check for McpAsyncRequestContext (nor McpSyncRequestContext either, for that matter), but only for the deprecated McpAsyncServerExchange?

mcp-annotations/mcp-annotations/src/main/java/org/springaicommunity/mcp/adapter/PromptAdapter.java

Line 66 in b8aea21

if (McpAsyncServerExchange.class.isAssignableFrom(parameter.getType())

Also, I am not sure this code even works for McpAsyncServerExchange, because it uses its own private "helper interface" instead of the real McpAsyncServerExchange one.
