Threads an optional nameLa field through SanctoralIdentity/SaintRecord/ TemporalFeastRecord/ActiveOctave so day-label.ts can render real Latin proper names instead of always falling back to English. Authors the proof set: all 11 named temporal feasts plus St. Lawrence (chosen to exercise the octave-headline and octave-commemoration code paths too).

// Resolves two sanctoral candidates wanting the same day — the case
|
|
// calendar/feasts.ts explicitly doesn't cover (it just picks the
|
|
// higher-ranked of several native candidates and drops the rest) and that
|
|
// calendar/commemorations.ts doesn't cover either (that's temporal-vs-
|
|
// sanctoral, this is sanctoral-vs-sanctoral). This is specifically what a
|
|
// transferred feast (calendar/transfer.ts) runs into when its landing day
|
|
// already has a native saint — never triggered by a plain ferial landing,
|
|
// since a genuinely empty day isn't a collision at all.
|
|
//
|
|
// Same ordering as commemorations.ts's FeastClass scale, which is exactly
|
|
// the point: `duplex > semiduplex > vigil > simplex` is that scale, not a
|
|
// separate one — see calendar/types.ts's FeastClass doc comment.
