The ACTIVITY sync cursor is a single (deviceId, dataType) timestamp shared by
the steps, active-calories and distance syncers. The cursor advances to the
latest record produced by any of them. When a device delivers calorie/distance
detail for the most recent minutes before the matching step detail, the cursor
moves past those minutes on the calorie front; the step minutes that arrive on
the next sync are then clipped by the slice start boundary and lost forever.
Resetting the HC sync state recovered them, confirming the data was present in
the database but skipped.
Give the per-minute steps, calories and distance records a deterministic
clientRecordId (gb-{type}-{manufacturer}-{model}-{endEpochSecond}) so that
re-emitting a record upserts instead of duplicating, mirroring SleepSyncer.
With records now idempotent, extend the per-syncer slice lower bound backwards
by a one-hour lookback so the trailing window is re-emitted on the next sync
and the late minutes are recovered. Heart rate is a grouped series keyed on its
start time, cannot be deduped this way, and does not extend the shared base, so
it keeps strict boundaries and never re-emits.
