First phase of syncing phone-logged manual/off-app workouts to the PC so they
count toward the unlock. This phase only establishes the cross-language wire
contract; no behavior change to existing flows.
- _manual_workout.py: build_sync_payload(draft, date) = build_entry fields +
a `kind="manual_workout"` discriminator + the workout's own `date`; and
manual_sync_record_id(date, start) -> stable `manual:<date>T<HH:MM>` id.
A StrongLifts session payload has no `kind`, so an ingesting PC can route on
it and never mistake a manual for a verified session.
- test_manual_workout.py: TestSyncWireFormat pins the exact literal payload as
the cross-language contract (the Dart workout_app test will reproduce the
same literal byte-for-byte; neither side's own round-trip test catches drift
from the other).
- workout_app/lib/models/manual_workout_constants.dart: hand-maintained mirror
of the 7 MANUAL_WORKOUT_* constants + the kind value (Python stays source of
truth; the shared fixture is the drift tripwire).
