FIRMWARE_UPDATE and ALARMS were already copy-pasted into all 6 device-type
registries by hand; POWER/KIDS_LOCK/REMOTE_CONTROL into 5 of 6. Consolidate
into two bundles in common.py, unpacked via *common.UNIVERSAL / *common.POWER
the same way ignored.IGNORED already is:
- UNIVERSAL: ALARMS, ENERGY_METER, FIRMWARE_UPDATE (moved from fridge.py),
SELF_CHECK (moved from fridge.py), AI_ENERGY_LEVEL, and the kids-lock/
remote-control pairs. Safe everywhere -- discover() only binds a href
actually present in a device's dump, so a capability with no known
conflicting family is a no-op where the href is absent and a real,
wanted entity where it's present. This also broadens AI_ENERGY_LEVEL,
ENERGY_METER, and SELF_CHECK to device types they weren't confirmed on
before, on the same reasoning.
- POWER: just POWER_GENERIC/POWER_VS_FALLBACK, applied to the 5 non-AC
registries. Airconditioner keeps its own opt-out: its climate entity
already owns /power/0 and /power/vs/0 via a bare, no-entity claim
(airconditioner.COVERAGE), and a real power capability on the same
href would make _build() raise (a href with multiple caps requires
every cap to have rt_filter or match_fn; the bare COVERAGE cap has
neither).
Full test suite (327 tests, all 6 device-type golden fixtures) passes
unchanged -- none of the newly-broadened capabilities bind on any existing
fixture, confirming the no-op reasoning held in practice, not just theory.
