An interface without properties says beside its name what Alexa has to know
of it; the library left both out. With a board and Alexa on 2026-09-28 the
discovery of a doorbell was accepted (202), the endpoint was not listed, and
its DoorbellPress was answered with 500 INTERNAL_SERVICE_EXCEPTION.
DoorbellEventSource now always carries "proactivelyReported": true.
SceneController carries "supportsDeactivation", false until the sketch calls
setSupportsDeactivation(true); on another interface the call is refused and
logged. The Scene example says that it can be undone.

AlexaStatusMessage gets a helper for color, percentage, power level, range, mode, lock state, contact,
motion, humidity and the thermostat (target, lower and upper setpoint, mode), and addProperty(row, place,
value) for a property without one. Each is a function of its own on one shared builder; a value outside of
the range of its property is reported as the nearest of the range with an error.
AlexaResources.h holds the 103 asset ids of resources-and-assets.html (AlexaAssets, AlexaUnits); AlexaState
has the seven states that were missing; addStateMapping() takes a number of any type.
A setter that refuses its argument makes isValid() false, and the capability is left out of discovery with
an error instead of being announced without what was refused.

AlexaCapability replaces the header-only AlexaInterface as what a device holds: 116 bytes with fixed places for
3 names, 4 action mappings and 2 state mappings, no std::vector or std::string. AlexaInterface and AlexaActions
stay as 1.x names; the five examples compile unchanged and announce the same bytes.
addCapability(row, instance) adds several capabilities of one generic controller. An instanced interface without
an instance or a name, an instance or semantics on an interface that takes none, and a full store are refused
with an ERROR line that says what to change.
PlaybackController and WakeOnLANController announce "properties": {} (AIF_EMPTY_PROPERTIES).
