Simplify frame header to message_type + payload_length (6 bytes)

Browse Source 
Removes channel_id from the header. All message-specific identifiers
(stream_id, request_id, etc.) now live at the start of the payload,
interpreted by each message type handler. A relay seeing an unknown
type can skip or forward it using only payload_length, with no
knowledge of the payload structure.
