v2.2.3

Fixed

• All-day events are no longer invisible in the month view. Skylight stores all-day events as start-midnight → next-day-midnight (exclusive end) and the month view draws the bar from that span, so zero-duration all-day events created from date-only input (start == end) showed in week/agenda views but rendered nowhere in the month grid. The server also silently floors any non-midnight end back to midnight, so end-of-day workarounds revert. Both create tools now expand a date-only endsAt on all-day events to the next day automatically; endsAt is documented as the last day of the event, inclusive.
