GenServer that deserializes TDLib JSON into Elixir structs and forwards them to the app.

Receives raw JSON strings from Sexy.TDL.Backend, decodes them, and recursively converts nested @type objects into the corresponding Sexy.TDL.Object.* structs.

Started automatically by Sexy.TDL.Riser — not called directly.

Event types

The handler forwards deserialized objects to app_pid as {:recv, struct} (e.g. %Sexy.TDL.Object.UpdateNewMessage{}). System and proxy events ({:system_event, type, details}, {:proxy_event, text}) are sent to app_pid directly by Sexy.TDL.Backend.
