feat(ef): the Gloria in excelsis, RG 431-432, deferring to Breviary 237-238

Phase 2 of celebrant-rubrics-phase1: colitur rubrics gains a fifth
column, whether the Gloria is said. Follows the Creed's own seam
exactly -- Rite.t.gloria, Liturgical_day.t.gloria, wired through
calendar.ml the same way.

RG 431(a)/432(a) defer the Gloria to the Breviary's own Te Deum rule
(nn. 237-238), so te_deum is implemented as its own named predicate,
cited clause by clause, not collapsed into a colour heuristic. 431(c)
(Holy Thursday, the Easter Vigil Mass) and 432(b)/(d) (violet; a
Requiem) are independent overrides checked ahead of the Te Deum-derived
answer. Every clause this engine has no dimension to model
(votive Mass classes, the wider n.302 "Missa festiva" categories) is
stated as N/A with its own reasoning, not silently dropped.

Validated against the FIUV universal Ordo (Gloria and Te Deum) and all
three LMS editions (Gloria). A first pass over-trusted a clean-looking
15-for-15 FIUV contradiction of 237(b)'s own Septuagesima exception and
replaced it with a blanket "every Sunday" rule; the evidence was itself
corrupted -- the FIUV extractor recognised only one of the source's two
Te Deum negations ("non dicitur", not "sine"), so every "sine Te Deum"
Sunday read wrongly true. Fixed in tools/extract_fiuv_ordo.ml, fixture
re-extracted, and the literal 237(b) reading restored once the
corrected data confirmed it. A second bug surfaced alongside it (Palm/
Passion Sunday wrongly reading true via Temporal_ef.named's own table
membership, then Christ the King wrongly reading false from an
over-broad fix) is closed with an explicit two-slug exclusion.

Domain-wide 1583-9999: every violet or Rose day is gloria=false except
the Easter Vigil (RG 431(c) lex specialis), every Requiem is
gloria=false, both measured exhaustively, zero exceptions. Mutation-
proved: disabling 431(c) reddens 8 tests including all four oracle
comparisons; disabling 238(c)'s feria-I-classis exclusion reddens
exactly the dedicated Ash Wednesday unit test, a genuine blind spot in
both oracle layers, reported rather than hidden.

Two open, cited findings, neither fixed here (out of this task's
"follow creed's exact seam" scope): a privileged Lenten/Passiontide
feria carrying one commemoration reads Gloria=true in the LMS Ordo but
Te-Deum=true/Gloria=false in FIUV -- the two oracles disagree with each
other, not merely with colitur (data/ef/expected-divergences-lms.sexp
L5, expected-divergences-fiuv.sexp F3); and a pre-existing, uncited
Colour.Violet bug on Rogation Monday/Tuesday in Temporal_ef.temporal,
surfaced by this comparison but root-caused as a separate defect (L6).

day/readings verified byte-identical against a build from the branch
tip before this task (v0.10.1's own tag predates an already-landed
bissextile fix that legitimately changed both, so it is not the right
baseline).

671 tests green (dune test); 678 with the exhaustive sweep
(COLITUR_EXHAUSTIVE_SWEEP=1 dune test --force, ~104s).
