feat: EF temporal Sunday lectionary (offline Sunday Mass readings)

Unique temporal-day slugs (season-sunday-week); scripts/genlect.go generates
tridentine-lectionary.ini from missalemeum keyed by slug (55 entries: the
Sundays of the whole EF year). caldata.TemporalReadings(form,slug) lookup;
--liturgy resolves proper-of-feast else the temporal cycle and renders the text.
bible.ParseRef strips abbreviation dots (1 Cor. -> 1 Cor). 52/53 Sundays fully
resolve offline.
