Add deut, this pool's first genuine original composition

User found a lead reading a patristic homily (English/Sancti/01-02.txt)
that quotes Deut 32:11's eagle image. Deuteronomy has no historical
Matins responsory anywhere in the reference source, so unlike every
other entry in this pool, this one is composed rather than
transcribed: a real R./V. pairing built from the Canticle of Moses'
own genuine verses (Latin/Psalterium/Psalmorum/Psalm226.txt, sung at
Lauds), verified against data/scripture/deut-32.yml to confirm the
citation is standard verse 11 and not the breviary's own internal
chant-verse-numbering (32:15-16) for the same text. Documented plainly
in the data file's own header as vu's composition, not presented as
historically attested.

63 of 72 bible-plan books now seeded. npm test (2029 passed) and
tsc --noEmit pass; live-verified through getBiblePlanReadings.
Canonical-key audit re-run, clean.

+### Matins responsory pools: `deut` — the first genuine original composition, not a transcription (2026-09-05)
+
+User found a real lead while reading a patristic homily (`English/Sancti/01-02.txt`, on Matt
+23:37 "O Jerusalem, Jerusalem"): it quotes Deut 32:11's eagle image in passing ("as also it is
+written... an eagle stirreth up her nest... spreadeth abroad her wings"). Confirmed the verse
+number against `data/scripture/deut-32.yml`'s own `n: 11` — genuinely Deut 32:11 in standard
+citation, not the breviary's own internal chant-verse-numbering for the same text (which splits
+it as 32:15-16 in `Latin/Psalterium/Psalmorum/Psalm226.txt`, the real Canticle of Moses sung at
+Lauds — that file supplied real, properly accented liturgical Latin and its English counterpart
+gave the matching translation, so no accentuation had to be guessed).
+
+Unlike every other entry in this pool, Deuteronomy genuinely has no historical Matins responsory
+anywhere in the reference source (confirmed absent from both Tempora and Sancti in the two prior
+entries) — so this one is composed, not transcribed: a real R./V. pairing built entirely from
+that same canticle's own genuine verses (32:15's eagle image as the R., 32:13-14's "apple of his
+eye" as the V.), verbatim text, not paraphrased or invented, just newly paired. Documented plainly
+in the data file's own header comment as vu's own composition rather than presented as a
+historically-attested responsory, matching this project's "not a reconstruction" ethos.
