MCP notifications

Tag 10: the server relays the container’s subscription to the notifications of the client’s servers; the client answers with one channel response per notification, an error last, and the channel response finish, each relayed to the container.

The server opens this channel when the container’s proxy opens a notifications channel on the begin scope. Every channel response is relayed to the container as one channel response.

• The request. The tag byte 10 and nothing more. Request states its form.
• The response. One channel response per notification, an error last when the client sends one, and the channel response finish. Response states the sequence.
• The conduit. The server relays each channel response onto the proxy’s channel as one channel response, in order, and finishes it when the channel finishes. A client connection that ends leaves the proxy’s channel unfinished.
