The FIRST session's Welcome runs before any backend construction
(vdisplay::open happens at display prep, after the Welcome), so the
capability probe's vdm() expect panicked the very first handshake of a
fresh service — the client saw a dead connect and auto-wake kicked in.
init() is idempotent and the driver facade is a unit struct, so the
probe now initialises the manager itself. Found on-glass (.173, first
Mac-client connect), fix deployed there.
