feat(routines): ship sourced weekly tasks for ZZZ and Endfield

Ridu Weekly (1,300 points) and the Weekly Routine (10 points), each with
the page that states it and that page's own date, so a figure from an
old guide shows its age. Routines share the task shape, so they draw and
count like a reader's own.
