Meal-slot checkpoints move from whole hours to minute-of-day ints
(0..1439) in the pure model and slot arithmetic of both languages:
MealSchedule(first_minute, last_minute, count) / (firstMinute:,
lastMinute:, count:), interior slots snapped to the 15-minute grid,
endpoints exact, integer-only. New: nearest_slot, satisfied_slots,
slot_fields / entry_slot_minute (additive "slot_min" wire field) and
schedule_to_wire / schedule_from_wire ("fm"/"lm" only when off the hour,
so whole-hour data stays byte-identical), parse_hhmm.
tests/fixtures/meal_schedule_vectors.json (scripts/
build_meal_schedule_fixture.py) is read by both suites; kuchnia_day.json
slot values regenerated as minutes.
Consumers (CLI, gate, storage, sync, app screens, kuchnia, notifications)
are intentionally broken until phase 2. patch-targets skipped: it fails
only because diet_guard._gatelock no longer imports.
