Bulk-convert the bible-plan TSV into Matins reading data

Converts all ~369 non-blank rows of the user's own scripture-reading
plan TSV into data/hours/bible-plan/*.yml, mapping each row's day label
to this app's (temporalId, weekday) or Dec25-Jan13 calendarDate scheme.
Fixes a few source TSV typos in the process (chapter-range and
trailing-colon citations); status stays explicitly `missing` pending the
separate Vulgate/Douay-Rheims import.

+### Bible-plan TSV — bulk conversion done (2026-08)
+
+All ~369 non-blank rows of the user's own bible-plan TSV (`~/Downloads/bible-plan.tsv`, 390
+lines including section headers/blanks) are now converted into `data/hours/bible-plan/*.yml`
+— 366 newly generated this pass, plus the 2 proof-date files already authored (`advent-3-tuesday`,
+`post-pentecost-15-sunday`). One row (Ascension Thursday) has no readings in the source and
+was correctly skipped — an honest gap in the user's own plan, not a conversion miss.
+
+Conversion was mechanical (script, not hand-authored per file): each TSV "Day" label maps to
+this app's `(temporalId, weekday)` scheme via the same rules `calendar/temporal-id.ts` uses
+(ferias inherit their governing Sunday's id — e.g. "Ash Wednesday" → `quinquagesima`/`wednesday`,
+"Nth Sunday after Trinity" → `post-pentecost-(N+1)` per the existing display-label convention),
+or to a fixed `calendarDate` for the Dec 25 - Jan 13 stretch per the reading-pool redesign
+above. Each `Reading N` column becomes its own `passages` entry; a chapter range like "Isa 36-37"
+expands to one passage per chapter, matching the two proof files' own convention. Every
+generated file sets `status: { la: missing, en: missing }` explicitly (not inferred), same as
+the proof files — correct even where a handful of citations happen to land on already-authored
+`src/data/scripture/*.yml` chapters (e.g. `cant-1`, `cant-8`, `sap-4`), since "verified" should
+mean a human confirmed the reading, not that text merely happened to resolve.
+
+A handful of book-abbreviation typos in the source TSV were fixed during conversion (not
+preserved as authored): "Dt 19-2020" → Dt 19-20, "1 Mach 9-10-11" → 1 Mach 9-11, two
+trailing-colon citations ("Mt 7:", "lk 17:") → whole-chapter references. Two day labels were
+garbled by an apparent TSV row-merge artifact ("4th Sunday after Easter of 4th Week after
+Easter", "Sunday after Ascension of Week after Ascension") — both parsed correctly by matching
+just the leading "Nth Sunday after Easter"/"Sunday after Ascension" phrase and ignoring the
+trailing garbage; not fixed in the source file itself since it wasn't touched.
+
+One real content question, not a bug: "Sunday after Ascension" 's row has a Gospel reading
+(Jn 17) as its third column — the only Sunday row in the whole TSV with one, seemingly
+contradicting the design note that the user's plan "never assigns a Gospel on a Sunday" (see
+memory `vu-matins-design`). Confirmed with the user (2026-08) to keep it as authored rather
+than drop it — read as a deliberate exception for this specific Sunday, not an authoring slip.
+`npm test` (359 tests, unchanged — these are new content files, not yet covered by any test
+table) and `npm run build` both pass.
+
+**Not done in this pass:**
+- No verse text was imported — every row still resolves its scripture citation against
+  whatever's authored in `src/data/scripture/` (a handful of chapters) and otherwise renders
+  `missing`, per the deferred bulk Vulgate/Douay-Rheims import above.
+- Not yet added to any test table (`tests/hours/matins.test.ts` still only covers the two
+  original proof dates) — bulk content isn't spot-verified against a live reference breviary
+  the way individual saints/feasts are elsewhere in this project.
