Extend the Fitbit / Google Health provider with the remaining sync
resources, driven by the existing syncUserFitbit orchestrator.
Activity (daily cumulative): steps -> ACTIVITY_STEPS, distance ->
WALKING_RUNNING_DISTANCE, the active-energy portion -> ACTIVE_ENERGY_BURNED,
floors -> FLIGHTS_CLIMBED, and VO2 max -> VO2_MAX. Each daily total mints a
stats:<tag>:<YYYY-MM-DD> externalId so a re-fetched day overwrites in place
rather than duplicating, matching the Apple-Health daily-total contract. The
running totals preserve a legitimate zero (a rest day is real data); VO2 max
stays strictly positive (daily latest-wins).
Sleep: map a session's per-stage segments to per-stage SLEEP_DURATION rows
(minutes; measuredAt = the stage end), harmonised onto the shared SleepStage
enum (light -> CORE, deep -> DEEP, rem -> REM, awake/restless -> AWAKE,
in-bed -> IN_BED, classic asleep -> ASLEEP) so the night-total and hypnogram
readers consume the same shape they already read for WHOOP and Apple.
Workouts: map exercise sessions to Workout rows keyed (userId, FITBIT,
externalId), with sport-type, start/end, duration, energy, distance, and HR.
Cross-source twins stay distinct at ingest; the read-time canonical picker
collapses them via the source ladder (Fitbit already ranked below WHOOP).
All three join the orchestrator's resource list and ride the per-resource
403 soft-skip so an independently-granted Restricted bundle that the user
withheld skips only its own resource. Rollups recompute and status-insight
caches invalidate through the shared upsert. No new MeasurementType, no
migration, no new dependency.
