A2A-specific JSON-RPC 2.0 error codes.

Standard JSON-RPC codes are in the -327xx range (parse, invalid request, method not found, invalid params, internal). A2A-specific codes occupy -32001 through -32007.

Every error is wire-shaped as:

%{"code" => integer, "message" => string, "data" => optional map}
