fix(lectionary): two Judith citations wrong in both engines

A live-missalemeum sweep over a full liturgical year (2028, 364 days)
returned 333 matching and 31 differing days: 17 already-known or pure
notation, 3 new. All three now adjudicated against the photographic
scans of the 1962 Missal.

The Assumption's Epistle reads "Iudith 13, 22-25; 15, 10" (scan1:35357).
Both engines carried "Judith 13:22-25; 13:15; 13:10" -- a chapter
carry-over defect that re-applied chapter 13 to the second citation and
so invented two verses the Missal never cites. The Seven Sorrows reads
"Iudith 13, 22 et 23-25" (scan1:36938, corroborated at 28468); both
carried "Judith 13:22; 13:25", dropping the range. The third, St Monica,
resolves the other way: the Missal gives 1 Timothy (scan2:32679, heading
and incipit both legible; scan1:29524 agrees) where missalemeum serves
the Common of Holy Women's Proverbs -- colitur is right, no change.

Layer 3 could not have found either citation defect. colitur's data is
bootstrapped from lectio, and lectio is the other side of that
differential, so while both engines produced the identical wrong answer
the comparison held it against itself and reported agreement -- the
shared-lineage blindness CLAUDE.md names, now with a second live witness
beside Holy Thursday's colour. Only an external oracle could see it, and
only outside the committed fixture's own window.

Fixed upstream in lectio, re-bootstrapped here (provenance SHA-256 moved
to 54f6bfc5, verified against the source), fixture regenerated.

The upstream fix inverted layer 3 from blind to load-bearing here:
reverting the Assumption citation now reddens both layers, where before
it would have reddened neither. Verified by mutation, both directions.

Allow-lists:
- C22 closed and removed (128 rows -> 0), not re-adjudicated -- the other
  engine was fixed to agree, the same shape as the C2-C5/C7/C9-C13/C21
  closures. Its own note had already flagged the Lenten Ember dead-key
  bug for upstream; lectio now also fails its build on any unreachable
  lectionary key rather than serving a plausible wrong Mass.
- M28 opened (3 rows, verdict colitur), pinning both sides' citation
  text rather than the date and diff shape alone, so a different
  divergence landing on the same date cannot be swallowed.
- M8's gate widened, expected_rows unchanged at 2: 2027-08-15 carries
  both its cause and M28's, and one entry is admitted per day. It stays
  under M8, which now requires its own commemoration difference to be
  present and admits the citation difference only when it satisfies
  M28's two-sided predicate. Neither cause absorbs the other.

layer_m_reason's oracle-row parameter, kept named since M2 closed for
exactly such a future reader, is live again.

A genuine LECTIO bug, reported here for upstream, NOT patched in this task (the brief's own triage rule). This is exactly the \"Holy Thursday was violet in both\" shape this project's own CLAUDE.md already names: layer 3 was STRUCTURALLY BLIND to this the whole time colitur also had the bug, since both engines independently produced the identical wrong answer -- a real illustration of why a passing differential means less here than it looks, not merely a citation elsewhere in this file's own header. Gated on the literal 3-slug list and `diffs = [ First_f; Gospel_f ]` exactly (slug/rank/colour already agree). Derived directly from the OCaml comparator's own failure output, not hand-counted first and cross-checked after: 128 (43 + 43 + 42 -- a few of the 46-year population are impeded by a competing sanctoral feast each year, so the Ember office itself is not always the observed day).")
