Connection

One MSP connection over newline-delimited JSON.

The connection sends your requests and commands, correlates their responses, enforces the frame-size limit, and hands inbound notifications and server requests to the handlers you register. It is transport-agnostic: pair it with any DuplexTransport. Most applications never build one directly — MuseClient.spawn or spawnMspConnection does it for you; reach for a bare Connection when you need the raw notification feed or your own transport.
