hours: build Terce, Sext, and None

Three separate resolver files (terce.ts/sext.ts/none.ts), not a shared
little-hour module — they're structurally identical but kept independent
by choice. Ordo verified against Divinum Officium (Monastic Tridentinum
1617): opening versicle, self-contained hymn, one antiphon framing three
psalms (no closing repeat, unlike Prime), a capitulum with its own
embedded short versicle/response, the day's own collect, and a closing
identical across all three hours.

Also fills in psalter-distribution.yml's previously-missing Sunday/
Monday/Tuesday psalm entries (Ps 118 sections for Sunday/Monday; Tuesday
turns out to share Wednesday/Thursday's native gradual-psalm set, not a
distinct one). Friday/Saturday's antiphons are derived from each day's
first psalm rather than reusing the native gradual antiphons, since
those two days already use a redistributed, non-native psalm set.

hours/types.ts gains a 'day-collect' part kind — the first ordo to use
the day's own Proper collect rather than a fixed text.
