Module client 

LAN MQTT client — the I/O layer.

One-shot, stateless cycle (connect → pushall → collect snapshot → disconnect), which suits a CLI invocation and respects the A1/P1 single-MQTT- connection limit. Built on rumqttc + rustls; the printer presents a self-signed certificate with no CA chain, so we accept any certificate while still validating the TLS handshake signatures.

StatusSource abstracts snapshot fetching so consumers (and tests) don’t depend on the concrete MQTT client.
