The household snapshot assembly that lived inline in the coordinator's
_async_update_data is extracted into a pure, Home-Assistant-free
core/snapshot.py: the QuestInstanceView / ChildDaySnapshot /
NestQuestSnapshot dataclasses, the _cycle_day helper, and a new async
build_snapshot(database, settings, today, time_zone) builder.
The coordinator is now a thin DataUpdateCoordinator wrapper that
resolves the local timezone and settings and delegates to
build_snapshot; the dataclasses and _cycle_day are re-exported from the
coordinator module so existing sensor.py / binary_sensor.py imports keep
working unchanged (entity_ids and per-child instance attribute payload
shape unchanged). The API service's panel snapshot route (next task)
shares this one implementation.
Tests that monkeypatched derive_state on the coordinator module now
patch core.snapshot.derive_state (the module that now owns the call).
A new test seeds a household and asserts build_snapshot's output equals
the coordinator's snapshot for the same database and date. Suite green
at 1588.
NestQuestCoordinator.async_refresh holds a per-entry lock so
overlapping service-path refreshes never interleave; the queued pass
always publishes after the in-flight one.
One refresh pass builds the whole entity snapshot: active children,
today's instances with derived open/done/missed states, per-child
presence via the PresenceEngine (records converted to model objects),
rollup counts, and the custody cycle day. Interval configurable via
the new update_interval option, default five minutes.
