Per IMPLEMENTATION-ORDER.md 1.4: a quest_definition_windows table
(definition_id, window, due_time) declares which day windows a
definition spans, one row per definition+window via the composite
primary key; window is CHECK-constrained to morning/afternoon/evening.
- const.py: WINDOW_MORNING/AFTERNOON/EVENING, QUEST_WINDOWS canonical
order, WINDOW_CLOCK_RANGES with the documented boundaries and the
boundary-to-later-window rule documented for Feature 07.
- schema.py: windows DDL joins SCHEMA_V1_STATEMENTS; due_time is
caller-validated strict HH:MM (DAO layer), matching the date policy.
- migrations.py: migration 4 is a plain CREATE IF NOT EXISTS statement
list (no rebuild needed for a new table).
- dao_rules.py: QuestDefinitionsDao gains upsert_window (idempotent
per window, due_time refresh in place), list_windows (const order),
remove_window; _validate_time/_validate_window helpers.
- tests: windows DDL shape/constraints (CHECK matrix, duplicate,
unknown definition), DAO round-trips, const range shapes; leak
guards extended to the new table.
