Author Common-of-a-Martyr/Apostle categories and St. Andrew's proper Matins psalmody

Two categories live-verified: common-of-a-martyr (from St. Ignatius of
Antioch, whose own office is entirely Common — also confirms
Common-of-a-Martyr-Bishop redirects to this same scheme, and that none
of its 3 Duplex+ saints has a proper antiphon of his own) and
common-of-an-apostle (from St. Bartholomew). St. Andrew authored as the
second saint-level proof, sharing the apostle category's psalm numbers
in every slot with his own proper antiphon text.

+### Matins psalmody overrides — category-keyed refactor + second proof, St. Andrew (2026-08)
+
+Refactored `hours/matins-psalmody-overrides.ts` per its own doc comment's flagged next step:
+`data/hours/matins-psalmody-overrides/` now splits into `saints/*.yml` (per-saint proper
+antiphon overrides, same shape as before, St. Lawrence migrated in place unchanged) and a new
+`categories/*.yml` store recording each Common category's own generic psalm-number/versicle/
+canticle-ref scheme, live-verified from a saint with *no* proper antiphon of his own (so his
+output is the category default outright). Two categories authored this pass:
+
+- **`common-of-a-martyr`**: from St. Ignatius of Antioch (2029-02-01, "vide C2" — entirely
+  Common, no proper text). Confirms Lawrence's one real deviation from the shared scheme worth
+  remembering: his own Nocturn 2 has Ps 16 where the Common default (and Ignatius) has Ps 64 —
+  a genuine proper substitution, not a transcription slip. Also confirmed (reference engine's
+  `CommuneM/C2a.txt`) that **Common-of-a-Martyr-Bishop's own Matins psalmody redirects outright
+  to Common-of-a-Martyr** — the two share one scheme, not two; checked all three Duplex+
+  Common-of-a-Martyr-Bishop saints on the calendar (Ss. Ignatius, Callistus I, Boniface of
+  Mainz) and none has a proper antiphon of his own, so this category currently has no saint
+  eligible for its own `saints/` entry under the proper-only policy below — a real, not
+  accidental, gap.
+- **`common-of-an-apostle`**: from St. Bartholomew (2026-08-24, generic "In omnem terram"
+  antiphon). Second live proof authored against it: **St. Andrew** (`saints/st-andrew.yml`,
+  2026-11-30, his own day outright that year), whose psalm numbers match the category's
+  generic scheme in every one of the 12 Nocturn-1/2 slots — only the antiphon text is his own
+  proper narration of his call and martyrdom. New scripture chapters authored for his Nocturn 3
+  canticles: `data/scripture/{isa-61,sap-3,sap-10}.yml`.
+
+**Category files are reference/documentation content only** — not consulted by
+`getMatinsPsalmodyOverride`, which still does a plain per-saint lookup exactly as before.
+Direct decision from the user (2026-08): a saint without their own `saints/` entry stays on the
+plain ferial-table fallback, never falls through to a category's generic antiphon text, even
+though that text is real and verified — "prefer real text over missing" is deliberately *not*
+extended to this case yet. The category files exist so the next proper-antiphon saint authored
+in an already-proven category doesn't have to re-derive/re-verify the same shared psalm numbers
+and versicles from scratch, and as the reference point for spotting a saint's real deviations
+(like Lawrence's Ps 16) from noise.
+
+Live-verified end-to-end: `tests/hours/matins.test.ts`'s new "second Duplex+ weekday-feast
+proof" describe block (Andrew's own psalmody resolving `verified` in both languages across all
+12 psalms + 3 canticles). `npm test` (374 tests), `npm run build`, and `tsc --noEmit` all pass.
+
+**Still open**: ~73 remaining Duplex+ saints across the other Common categories (Confessor,
+Confessor-Bishop, Virgin, Doctor, etc. — the largest population, per the earlier estimate) —
+each needs its own category file (one live `prayMatutinum` query against a no-proper-antiphon
+saint) before any of its own saints' proper antiphons can be authored against it.
