qconnect-lan gains what QBZ calls on another receiver: a
_qobuz-connect._tcp browser (own device_uuid filtered, Electron's SDK
floor), the get-display-info / get-connect-info probe (IPv4 first, 10 s,
Connection: close) and the connect-to-qconnect handoff body — the
controller's session uuid, the delegated API token and the delegated QWS
token under its LAN name jwt_qconnect, become_active. qbz-qobuz mints the
delegated pair with POST /qws/delegateAuth (q_app_id), the step every
official controller takes before the handoff. The receiver DTOs learn to
deserialize (unknown enum values collapse to Unknown). Pure helpers tested.
