test(oracle): compare reading citations against missalemeum

Layer 4 (test_oracle.ml) now extracts and compares the Epistle/Gospel
citation for every one of the 730 days in the 2026-2027 fixture, the
same axis Task 8 already added to layer 3. tools/
extract_missalemeum_oracle.py gained a structural citation-span
detector (the first "*...*"-wrapped span under 40 chars containing a
chapter:verse-shaped digit pair), verified exhaustively over all 1 458
Lectio/Evangelium sections. 728 of 730 days are comparable; the 2 that
are not (Good Friday, both years) have no such section in missalemeum's
own JSON at all -- a structural limit on the oracle's own side (M23),
not a colitur gap. 451 of 730 days differ and are all explained across
19 cited entries; 0 unexplained. Chain step 4 (the Commons) has no
layer-4 witness: confirmed empirically (a scratch sweep, not merely
re-asserted from Task 6's own report) that none of the 15 Commons/proper
saints is ever the observed office in this window.

The comparison surfaced three genuine colitur bugs in
data/ef/lectionary.sexp, all fixed at the source in
tools/bootstrap_lectionary.ml:

1. Holy Name of Jesus (ef-holy-name-sunday/ef-holy-name) carried a
   mis-derived citation, borrowed by analogy from an unrelated ini
   section ("ef-christmas-sunday-0", the Sunday-within-the-Octave's own
   Mass) on the wrong assumption the two share a Mass. Disproved by
   missalemeum's own extraction for both real Holy Name Sundays in its
   window, confirmed against the Missal itself, twice, both scans
   (Acts 4:8-12/Luke 2:21, not Gal 4:1-7/Luke 2:33-40).
2. RG 17(a)'s own "diebus ferialibus" rubric (immediately following the
   Holy Name heading, both scans) was never implemented: 2-5 January
   ferias repeat 1 January's Mass, 7-12 January ferias before Holy
   Family Sunday repeat Epiphany's, and Holy Family's own week has a
   named formula ("Missa Dominicae Primae post Epiphaniam"). All three
   fell to step 3's undifferentiated Sunday walkback instead. Fixed for
   three 5-weekday families, deliberately excluding Saturday from all
   three -- RG 78's BVM Saturday Office wins there unconditionally,
   confirmed against missalemeum's own title on this window's own such
   Saturdays.
3. Corpus Christi and Sacred Heart (both real, never-impeded I-class
   movable feasts) had no lectionary entry at all. Both engines
   independently fell back to Trinity Sunday's own citation and
   silently agreed on the wrong answer -- the "Holy Thursday violet in
   both" shape CLAUDE.md names for exactly this reason.

Because lectionary.sexp is shared with layer 3 (the lectio differential,
2005-2050), these fixes changed colitur's output for the whole domain,
not only 2026-2027. data/ef/expected-divergences.sexp and
test_differential.ml needed matching updates: C1 narrowed 361->173 and
C25 narrowed 57->13 (rows that now resolve correctly moved to new
entries), C16's note corrected (count unchanged), and six new entries
added (C29-C34, 397 rows total, all verdict colitur). test_lectionary.ml
and test_lectionary_ef.ml's own pins were updated to match (entry count
131->148; one step-3 regression test re-pointed to a date that still
genuinely exercises that step).

One entry, M26 (30 rows, verdict open), is a genuine unfixed gap: colitur's
step-3 "resume the preceding Sunday" fallback is its only ferial-Mass
mechanism, and missalemeum's own selection is more granular in three
confirmed ways (a rotating votive Mass of the BVM, a named weekly
formula for at least one week, and later Time-after-Pentecost weeks this
task's own investigation did not narrow to a single rule) -- the same
"needs a season-keyed selection mechanism, new behaviour not new data"
shape data/ef/expected-divergences.sexp's own C6/C25 and Task 6's own
residual concern already name, out of this task's own scope to build.
