- WV consumer-model prefix (FlexWash twin washers, e.g. WV55M9600AW)
wasn't in the by-model fallback map, so these units fell through to
the unknown-device registry with zero capabilities bound (#19).
- Washer/dryer combo units carry a writable dryLevel field directly on
/washer/vs/0 with no separate dryer resource; add a self-gating
select for it, off supportedDryLevel presence, so plain washers are
unaffected (#22).
