Author missing Matins Gospel pericopes across nocturn-readings store

~110 of 355 nocturn-readings files had a patristic homily with no
paired Gospel-pericope text -- the homily discussing a Gospel that was
never itself transcribed into the file. Closed in two waves (the first
pass's source-string regex missed many real cases where the citation
lived only in a header comment or wasn't named at all), each entry
sourced from divinum-officium-reference's own Missale files (following
Sancti/Commune redirects where a feast reuses another's Gospel) and
verified per file rather than assumed -- several candidates turned out
to be genuine Nocturn 2 content or Common-of-saints cross-references
with no proper Gospel of their own, correctly left untouched.

Includes both live-reported gaps: St. Joseph of Cupertino's own Bk. II
Homily 38 (Matt 22:1-14) and the Vigil of St. Matthew's Ambrose homily
(Luke 5:27-32).

TODO.md logs the closed item plus a new, distinct follow-up: a handful
of files with no Nocturn 3 content authored at all (not just an
unpaired Gospel), found along the way.

npm test (2029 passed) and tsc --noEmit both pass.

+# (isGospel: true, immediately before Gregory's homily) — reused
+# verbatim from `ss-cyriacus-largus-and-smaragdus.yml`, already authored
