(Migrated from github.com)

The engine omits the Vigil of the Ascension. The Wednesday before Ascension
(which is also Rogation Wednesday) resolves to the standalone rogation archetype
(IV class, violet) instead of the II-class vigil. Both oracles show II class, white.

Spec (verified against Rubricae Generales 1960)

Day: the Wednesday before Ascension Thursday (Easter + 38).
Class: II (rank 2). Colour: white (the vigil is the principal office and the
default Mass).
Citation: R.G. 1960 nn. 30–31 — II-class vigils are Ascension, Assumption,
St John the Baptist, Ss Peter & Paul. The Minor Litanies (Rogation) "are not
commemorated in the Divine Office" — the vigil is the principal office; the Rogation
is at most a Mass commemoration.

Implementation notes

Add an ascension-vigil archetype (kind vigil, rank 2, white).
The vigil (rank 2) must outrank the rogation archetype (rank 4) on that
Wednesday so the day resolves to the vigil, with the Rogation demoted to a
commemoration/variant — currently src/Temporal/Eastertide.php emits only the rogation.
Colour caveat (genuinely conditional): the Mass is white all day by default;
violet only if a parish sings the Rogation procession-Mass. Model the day as
rank 2 / white with the Rogation as a violet-Mass commemoration/variant — do not let
the procession colour become the day's colour. May want a conditional-colour
representation in the output contract (flag for the contract reviewer).

Surfaced by the #428 burndown. Resolves the Rogation-Wednesday corpus-rank-underranked
rows (o=2) and the mis-won St Augustine of Canterbury (2025-05-28) / St Robert Bellarmine
(2026-05-13), which should be commemorations under the vigil.
