Add reusable Matins building blocks: types, content stores, seed data

New ResolvedPart kinds (nocturn-psalmody, te-deum) and lesson fields
(nocturn, source, isGospel, responsory) in hours/types.ts. Three new
content-store modules: propers/bible-plan.ts (the user's own continuous
scripture-reading plan, replacing the historical Nocturn-1 lectionary),
propers/nocturn-readings.ts (general feast/temporal-day Nocturn 2-3
readings, extending propers/octave-readings.ts's combine-into-one-reading
pattern via a newly-exported resolvePassages), and
propers/matins-responsories.ts (a per-book responsory pool, matched
loosely rather than by exact citation).

Data: Sunday's fixed 12-psalm/3-canticle psalmody (live-verified against
the reference engine), the invitatory antiphon, ferial hymn and
capitulum, the Te Deum, a seeded Isaiah responsory, two live-transcribed
scripture chapters, and the two bible-plan rows needed for this pass'
proof content.
