Transcribe Monastic Vespers weekday psalmody from source

Sourced from Divinum Officium's explicit "[Monastic Vespera]" block
(Latin+English Psalmorum), not the ambiguous unlabeled Day/Daya tables
earlier in the same file — confirmed by cross-checking Monday's psalms
against the already live-verified Lauds antiphons, which the unlabeled
tables both got wrong. Only 4 psalms a day (Rule of Benedict ch. 17),
with two real wrinkles: Ps 115+116 joined under one shared antiphon on
Monday, and Ps 138/143 each split across two verse-ranges under one
shared antiphon (Thu/Fri) — modeled by letting a group's `psalms` list
take `{number, verses}` entries alongside plain numbers.

+# major.txt, "[Monastic Vespera]" (Sunday) through "[Monastic Vespera]
+# (feria 7)" (Saturday) — English parallel at the same section names in
+# .../English/Psalterium/Psalmi/Psalmi major.txt. Not a per-day live
+# prayVespera query (unlike lauds-antiphons.yml) — instead cross-checked
+# against Monday's Lauds antiphons, which *are* already live-verified:
+# "[Monastic Laudes] (feria 2)" in that same source file matches
+# lauds-antiphons.yml's monday entry word-for-word, including its Ps 35
+# antiphon, which two other unlabeled candidate tables earlier in the same
+# file ("Day1 Laudes1/2", "Daya1 Laudes") both got wrong. That match is
+# what confirms "[Monastic Vespera]" is the right block to use here, not
+# those unlabeled Day/Daya ones.

+# Only 4 psalms a day (Rule of Benedict ch. 17), not Roman's 5. Two real
+# wrinkles in how those 4 "slots" map to psalm numbers:
+#   - Monday's third slot joins Ps 115 and 116 under one shared antiphon
+#     (both short psalms, said back-to-back) — 'psalms' lists both.
+#   - Thursday's first slot (Ps 138) and Friday's second slot (Ps 143) are
+#     each one psalm split into two verse-ranges under one shared
+#     antiphon, each range getting its own Gloria Patri — 'psalms' lists
+#     two `{number, verses}` entries. Ps 144 is *also* split (1-9/10-21),
+#     but across two different days (Friday's last slot / Saturday's
+#     first), each with its own distinct antiphon — that's just two
+#     ordinary single-psalm slots, not a shared-antiphon pair.
+#
+# Underlying psalm texts for this range (109-147, minus the few already
+# authored for other hours) aren't transcribed yet — src/data/psalms only
+# has what Prime/Terce/Sext/None/Matins/Lauds/Compline needed so far.
