Merge branch 'fix/ef-precedence-defects': seven EF calendar defects

Fixes seven defects in the EF calendar, each found by differential and
oracle comparison against an independently-written engine and each
backed by a cited paragraph of the Rubricae Generales verified against
the 1962 Missal:

  RG 96  transfers must skip II-class days (the Precious Blood was
         landing on the Visitation)
  RG 91  a II-class privileged feria yields to an equal-class feast
         (St Matthew was losing to the September Ember Wednesday)
  RG 11  all Sundays of Advent, Lent and Passiontide are I class
         (only Advent I was), which also settles St Joseph on a Lent
         Sunday
  RG 131 Rose on Gaudete and Laetare, which the EF path never emitted
  RG 122 Holy Thursday is white

and the sanctoral generator itself, whose rank inference had tagged 15
III-class feasts as commemorations, dropped four entries to slug
collisions, and mis-tagged three class fields.

The EF oracle test asserted Season only, which is why none of this ever
failed. It now asserts rank and colour, with a cited allow-list.

Two commemorations had been deleted on a primary-source claim the
primary source contradicts: the Archivum Liturgicum transcription
silently drops commemoration lines where the photographic scans carry
them. Six of the seven affected dates are now present; the seventh
(25 December) is blocked by an ingestion limit that reads only the
first of three Christmas Masses, recorded at its cause.

Known gap, recorded in source: RG 95/97/98 chained transfers, where two
I-class feasts translate to the same day.

+//     the Nativity of the BVM, an undisputed ordinary Marian feast, on a
+//     Sunday -- 2019-09-08 -- shows the SUNDAY observed, the feast merely

+//     mysterio Domini, et vicissim" (a Sunday's office and a feast/mystery

+//     kept separate there from 120(a)'s own "Domini" heading. Both textual
+//     tests available (the calendarium's title, RG 120's own taxonomy)
+//     point BVM; the occurrence-behaviour evidence points Domini. This is a
+//     live, acknowledged disagreement with the primary text on the
+//     strength of oracle evidence about what the day actually DOES, not a
+//     claim that the text is wrong or ambiguous. See
+//     internal/calendar/precedence_ef_repro_test.go's

+//     (a feast of the BVM, calendarium: "Sanctissimi Nominis Mariae") --
+//     wrongly matching the latter too. Excluded whenever the title also
+//     names Mary. Unlike the Purification, this one is NOT contested: its

+//     I- or II-class feast. Nothing in this codebase's actual data currently

+//     about that is demoted throughout Lent is independently III class or
+//     lower, per the calendarium), but the function does not itself enforce
+//     it, so a future entry could reach it.
+//   - It is a proxy for "why was this saint never observed", not a citation.
+//     17-31 December is excluded from ever trusting the id-derived rank
+//     below, REGARDLESS of what this heuristic would otherwise say --
+//     covering BOTH of round 1's own late-Advent/Christmas-octave rank
+//     promotions, on two DIFFERENT strengths of evidence, recorded
+//     separately because they are not the same case:
+//     -- 26-31 December (RG 68(d)/(e), a positive citation): "die 29
+//     decembris, fit commemoratio S. Thomae Episcopi et Mart.; die 31
+//     decembris, fit commemoratio S. Silvestri I Papae et Conf." -- the
+//     calendarium names each a bare "Commemoratio" with NO class of its
+//     own, even though the DAY they fall on is II class (within the
+//     Nativity Octave). Two REAL entries (Thomas Becket, Silvester) are
+//     live here; see the call site's own comment.
+//     -- 17-23 December (RG 91 entry 18, a PRECAUTIONARY exclusion, not a
+//     positive citation): round 1 also promoted these late-Advent
+//     ferias from class-3 to class-2 (same lineage, same coupling
+//     shape as 26-31 December's own promotion). No live entry tests
+//     this range today -- the sole sanctoral entry there, `thomas`
+//     (21 December), is an OBSERVED class-2 feast reached via the
+//     harvestDate `obs` path, not this function's id-rank-trust path
+//     at all -- but unlike 26-31 December, there is no RG citation
+//     stating that a saint commemorated here has NO independent class;
+//     RG 91 entry 18 only ranks the FERIA, and (per defect 2's own
+//     finding) a genuine class-2 FEAST commemorated here would
+//     actually WIN against it (entry 16 above entry 18), so "the day
+//     is class-2" does not reliably explain a class-2 saint's absence
+//     the way it does for 26-31 December's own two named cases.
+//     Excluded anyway, on the side of the KNOWN-safe default
+//     (RankCommemoration) rather than risk repeating the identical
+//     failure shape the day this range's own first real entry arrives.
+//
+// This is also a warning about a structural hazard, not just a boundary
+// fix: this function calls calendar.Compute, i.e. it reads the ENGINE's OWN
+// computed temporal ranks to decide what DATA to generate. A change to
+// temporal_ef.go's ranking (e.g. round 1's own 17-23/26-31 December
+// promotions, RG 91 entry 18 / RG 67-68) can silently flip this function's
+// verdict and rewrite generated data with no code change to this file at
+// all -- confirmed by direct measurement, not just reasoned about: running
+// this function's body against the branch-point engine versus the current
+// one over the six reference years flips the verdict on 50 dates across
+// exactly these 13 MM-DD values (12-17 through 12-23, 12-26 through
+// 12-31), no others. Any future temporal_ef.go rank change should re-check
+// this function's own boundary cases, not just its own tests.
+//
+// harvestDate keeps a saint's commemoration id rank ONLY if every reference
+// year in which it was seen returned true here -- a single false (an
+// unprivileged day, or the December exclusion) is enough to fall back to
+// RankCommemoration, the safe default (see St Blaise, whose own
+// commemoration id claims rank 4 and is still correctly overridden to
+// RankCommemoration, proving the id's rank is a candidate, not a verdict --

+//     Dedication of the Archbasilica; a `return` there drops Theodore for
+//     good).
+//  2. The tempFeastSkip/Christ-the-King check used to `return nil, comms`
+//     outright -- correct for tempFeastSkip's three permanently-fixed dates
+//     (every year behaves the same, so nothing is lost), but wrong for

+//     immediately there discarded "St. Evaristus", visible only in the OTHER
+//     five years. `continue` fixes both: the loop keeps trying every
