using week numbers accounts Sunday through Saturday, not Monday through Sunday

[smemsh]

Week numbers would typically be ISO weeks, but they seem to include the Sunday from the previous week, and not include the Sunday from the given week. For example:

timew summary 2024-W10 - 2024-W11

includes Sunday from W9 and does not include Sunday from W10. This differs from [imo correct] behavior of :week and :lastweek which use Monday based weeks. I would think week number would correspond exactly to date +%V.

This was tested with timew-1.7.1 and its pegged libshared.

Got the week syntax from src/libshared/test/datetime.t.cpp. Was not sure if the bug should be filed in libshared repo, but it seems to be library-user-specific since :week and :lastweek are working as expected, but let me know if this should be moved there.
