"""RelayAdapter — one generic gateway adapter fronted by the connector. EXPERIMENTAL. A single ``BasePlatformAdapter`` subclass that, at handshake, receives a ``CapabilityDescriptor`` from the connector telling it which platform it is fronting and which capabilities to advertise to the ``GatewayStreamConsumer``. It implements the four abstract methods (``connect`` / ``disconnect`` / ``send`` / ``get_chat_info``) plus the capability surface (``MAX_MESSAGE_LENGTH``, ``message_len_fn``, ``supports_draft_streaming``) by delegating wire I/O to an injected transport and reading capabilities off the descriptor. There is NO per-platform gateway code: the connector is the only side that knows "this chat_id maps to a Discord channel, send it via the Discord websocket."
