Joshua King e9dc0a1445 Test fix: week 0 runs Mon Jan 5 through Sun Jan 11
The six-day preview expectation missed that Jan 10-11 are still in
the present week (the away week starts Jan 12). Suite green before

Joshua King 1bb0617471 Next-N-present-days preview (Feature 05, task 6)
PresenceEngine.next_present_dates(child_id, start_date, count):
walks forward from the INCLUSIVE start date through is_present, so
overrides and the pattern are honoured identically — this is the
preview the admin Schedule tab renders before a parent saves a
custody pattern. Count must be a positive int; the scan is capped at
two years (MAX_PREVIEW_SCAN_DAYS) and an always-absent child raises
a clear ValueError instead of looping forever. Tests: known two-week
pattern (straight five-day week, mid-week start skipping the absent
week), inclusive start, override blocking the preview start,
schedule-free child, input validation, always-absent error. Suite:
1002 passed.
