Add Matins psalmody overrides for a Duplex+ weekday feast

matins.ts's three-nocturn gate correctly governed nocturn count
(Sunday, or Duplex+) but wrongly reused the literal Sunday psalmody as
content for every three-nocturn day, including a weekday feast. Live-
verified (Monastic Tridentinum 1617) that a Duplex+ weekday feast has
its own genuinely different psalmody -- confirmed per-Common-category,
not per-saint, by cross-checking St. Lawrence against St. Ignatius of
Antioch (a different Martyr sub-category, nearly identical psalm
numbers, different antiphons).

New mechanism (matins-psalmody-overrides.ts, mirroring the Lauds one
but keyed per-category) with St. Lawrence authored as the live-verified
proof; falls back to the plain ferial weekday table, redistributed into
3 nocturns, for every other Duplex+ id until its own category's content
is authored. Also generalizes the canticle shape to support a citation
spanning multiple scripture chapters under one heading (Lawrence's own
Nocturn 3), and adds the new Sirach/Jeremiah chapters his canticles cite.

+# Verified against Divinum Officium (Monastic Tridentinum 1617), live
+# prayMatutinum query (2026-08-17, St. Lawrence's own octave closing day
+# -- "In Octava S. Laurentii Martyris ~ Duplex"). This is the live-
+# verified proof for the Matins-psalmody-override mechanism
+# (hours/matins-psalmody-overrides.ts) -- the general mechanism gap this
+# closes: a Duplex+ weekday feast previously fell through to reusing the
+# literal *Sunday* psalmody (data/hours/matins-sunday-antiphons.yml, Ps
+# 20-31) unconditionally, which is wrong -- a Duplex+ weekday feast has
+# its own real, different psalmody (confirmed against the live engine
+# directly), not the Sunday's.
+#
+# Cross-checked against a second Duplex saint (St. Ignatius of Antioch,
+# Common of a Martyr-Bishop, no proper content of his own, live-queried
+# 2029-02-01): Nocturn 1 is *identical* (Ps 1,2,4,5,8,10); Nocturn 2 is
+# nearly identical (Ps 14,20,23,63,91 match -- only one slot differs,
+# Lawrence has 16 where Ignatius has 64). So the psalm *numbers* are a
+# shared per-Common-category pool, not unique to Lawrence -- only the
+# antiphon *text* is proper to him (each one narrates an episode of his
+# own martyrdom, e.g. "Quo progréderis sine fílio, pater?"). This file is
+# keyed by his own saint id (not yet a Common-category id) since only his
+# own proper antiphons have been authored so far -- see this module's own
+# doc comment for what extending this to a real Common-category key would
+# need.
+#
+# Nocturn 3's first canticle spans two Sirach chapters under one heading
+# in the source ("Eccli 14:22;15:3-4;15:6") -- kept as one canticle with
+# two refs (matins.ts's own `canticles: { refs: [...] }[]` shape), not
+# split into two, matching how the live engine presents it. New scripture
+# chapters authored for this: data/scripture/{sir-14,sir-15,jer-17,sir-31}.yml
+# (all sparse, only the cited verses -- same convention as sir-36.yml's
+# own Sunday-canticle transcription).
