Corrected an earlier "no source exists" claim by live-querying real
commemorated instances of the Vigils of St. Lawrence and the Assumption
across six different weekdays. Their source files' own [Rule] block
("Versum Feria") turns out to be a real, sourced mechanism, not an
absence: a mere commemoration doesn't reuse the vigil's own antiphon at
all -- it borrows the plain ferial day's antiphon/versicle instead, and
that antiphon quotes the Benedictus canticle in weekday sequence (same
shape vespers-magnificat-antiphons.yml already uses for the Magnificat).
The versicle is a single fixed text. Sunday has no entry: a Vigil
transfers off an ordinary Sunday rather than ever reaching a
commemoration there, confirmed live as well as already true in this
app's own precedence rules.
sanctoralCommemorationPart now takes weekday and resolves this
dynamically for common-of-a-vigil saints, rather than needing a static
per-saint file. All 218 saints with an authored collect now have a real
commemoration antiphon.
