Make LoggingMessageNotificationParams.Data required per MCP spec#1353
Conversation
The MCP schema defines `data` as required in LoggingMessageNotification params. Change from `JsonElement?` (nullable, optional) to `required JsonElement` (non-nullable, required) to match the spec. JsonElement remains the correct type (not JsonObject) because the spec defines data as typeless (any JSON-serializable value), not restricted to JSON objects.
