scripture: add a dedicated non-Psalm scripture store, migrate pure-scripture readings

Adds src/scripture/ (types.ts, index.ts), a verse-addressable store mirroring
psalter/index.ts's own pattern exactly -- getScriptureVerses(book, chapter,
range) -- for non-Psalm scripture (Wisdom, Canticles, Ezekiel, Acts, Joel,
etc.). Kept as its own module, not folded into the Psalter, per 2026-08
discussion ("the psalms kind of work differently even if the logic is the
same, they do need their own store").

Octave readings can now declare `passages: [{ book, chapter, verses }]`
instead of embedding text -- each entry becomes its own paragraph, letting a
reading built from several verse ranges keep its original paragraph breaks.
getOctaveReading resolves either shape (embedded text or passages) into the
same OctaveReadingText callers already expect, so nothing downstream needs
to know which was used. Scope, per discussion: only readings that are
Scripture start to finish get this treatment -- prose that merely quotes a
verse or two (most of the patristic sermons pulled so far) keeps its
quotations embedded inline, as before.

Migrates the 9 already-committed octave readings that are pure Scripture
(Wisdom 4:7-20, Canticles 1 and 8, seven different Ezekiel excerpts across
All Saints' octave -- one of which, day 7, genuinely spans two chapters --
and Acts 19/Joel 2 for Pentecost's octave) to the new passages notation,
verified to resolve to character-identical text as before.

-    Lesson from the book of Wisdom Wis 4:7-12 7 But the just man, if he be prevented with death, shall be in rest. 8 For venerable old age is not that of long time, nor counted by the number of years: but the understanding of a man is grey hairs. 9 And a spotless life is old age. 10 He pleased God and was beloved, and living among sinners he was translated. 11 He was taken away lest wickedness should alter his understanding, or deceit beguile his soul. 12 For the bewitching of vanity obscureth good things, and the wandering of concupiscence overturneth the innocent mind.

-    Lesson from the book of Wisdom Wis 4:13-16 13 Being made perfect in a short space, he fulfilled a long time: 14 For his soul pleased God: therefore he hastened to bring him out of the midst of iniquities: 14 But the people see this, and understand not, nor lay up such things in their hearts: 15 That the grace of God, and his mercy is with his saints, and that he hath respect to his chosen. 16 But the just that is dead, condemneth the wicked that are living, and youth soon ended, the long life of the unjust.

-    Wis 4:17-20 17 For they shall see the end of the wise man, and shall not understand what God hath designed for him, and why the Lord hath set him in safety. 18 They shall see him, and shall despise him: but the Lord shall laugh them to scorn. 19 And they shall fall after this without honour, and be a reproach among the dead for ever: for he shall burst them puffed up and speechless, and shall shake them from the foundations, and they shall be utterly laid waste: 19 They shall be in sorrow, and their memory shall perish. 20 They shall come with fear at the thought of their sins, and their iniquities shall stand against them to convict them.
