Wires the Python side to the configurable schedule. No edit surface yet, so nothing writes a schedule and current_schedule() returns the default -- the derived hours are still 08/12/16/20 and the cutoff is still 22:00. Verified by running it: before any edit the slots are unchanged, after recording 08-20 x5 they become 08:00, 11:00, 14:00, 17:00, 20:00, and a 2020 day still resolves to the four-meal schedule. _slots.py now takes the schedule as a *required* argument rather than reading module constants. Required, not defaulted, on purpose: a default would let a call site missed in this refactor keep deriving the old fixed hours on one device, and a slot one device offers while the other does not is a checkpoint that can never be satisfied. Making it required let mypy enumerate the nine call sites instead of trusting a grep. The history is forward-only and seeds the default at the epoch *before* recording today's value, so switching to five meals leaves past days judged against the four-meal schedule they actually ran under. Same shape and same reasoning as _budget_history.py; it will ride the same CRDT record. Two details worth naming: - MEAL_SCHEDULE_FILE lands in DATA_DIR, so conftest's _isolate_state redirect is patched in this same commit rather than a later one. Confirmed with a canary that the redirect is live and that ~/.local/share/diet_guard/ has no .meal_schedule after a full run. - _mcp_read imports _budget.current_schedule already, so the meal-schedule lookup is aliased rather than shadowing it. _gatelock._pending_slots is spelled `is None` rather than `or` now. The two are in fact equivalent -- if 0 is a slot it is necessarily the first slot, checked exhaustively -- but the intent should not rest on that coincidence. 761 tests, 100% branch coverage.

# --- Gate (log-to-unlock) ---------------------------------------------------

|
|
# that slot must carry a logged meal or the screen locks until it does. This
|
|
# makes tracking fully automatic (you are prompted on a schedule rather than
|
|
# trusted to log voluntarily) and nudges regular eating. Coming home late
|

|
|
# backfills the whole day, which is the "requirement to access the PC" behavior.

# --- Sync (cross-device log merge) ------------------------------------------
