Parameter decorator for an MCP tool's input arguments.
@McpRoute.Params<T>() validates the arguments object from a
tools/call request against the TypeScript type T using typia. A failed
validation surfaces to the client as a JSON-RPC -32602 (InvalidParams)
error with structured diagnostics, giving the LLM precise feedback to
self-correct.
MCP tools accept exactly one arguments object; applying this decorator more
than once on a single method is a compile-time error. The decorated type
T must be an object type without dynamic properties.
