feat(of): assemble Rite_of.context and wire --rite of into the CLI

Task 5 of Phases 3-5 (the payoff task): bundles Tasks 1-4's separately
built pieces (Temporal_of, Precedence_of, Rubrics_of, Lectionary_of)
into a (Vocab_of.season, Vocab_of.rank) Colitur_kernel.Rite.t, and
wires colitur day/readings --rite of <year> into the CLI. Default
stays ef; every pre-existing invocation is byte-identical (asserted
directly in test/cli.t and against a real v1.0.0 build for three
years, plus git diff --stat v1.0.0..HEAD over lib/rites/rite_ef/,
lib/kernel/, data/ef/ is empty).

No kernel change was needed, confirming the spec's central claim.
season_runs needed real thought rather than the brief's own suggested
Vocab_of.seasons: Temporal_of.season's own 'first run'/'second run'
comments confirm Ordinary Time is genuinely interrupted by Lent and
Easter over one liturgical year, so the expected run-length-compressed
sequence names it twice, six runs over five seasons -- exactly the
case Rite.t.season_runs's own doc comment already names as its
illustration for why this field is rite-supplied rather than derived.
easter/fixed_key are as specified, each carrying its own citation
(Gregorian computus; the 2002 Missal's one bissextilis occurrence is a
leap-year table entry, not a kalends-doubling rule, so fixed_key is
identity).

Follows rite_ef.ml's template and its lectionary-parameter lesson
exactly: lectionary is caller-supplied, not closed over.

test/test_rite_of.ml resolves the real assembled rite (calendar-2002
.sexp + all 13 amendment overlays + lectionary.sexp) through Calendar
and Validate.run, the same discipline test_validate.ml/test_rite_ef.ml
already apply to EF. This is the first time rite_of has been checked
this way, and it surfaced two new, real, cited gaps outside this
task's own scope to fix: Temporal_of never reaches Normae n.35(a)'s
30-December Holy Family fallback in a year with no Sunday in 26-31
December (first hit 1583, the domain floor), and Temporal_of.anchors
disagrees with temporal on 24 December when that date is itself a
Sunday (Advent IV outranks the Vigil, first hit 2006). Both pinned as
known-wrong, not fixed, the same treatment the brief's own pre-known
St Joseph/Palm Sunday gap (Normae n.56(f)) gets, pinned on 2062. A
third gap was found in data/of/lectionary.sexp's own coverage (audited
against one civil year only, so the other weekday-cycle letter is
unaudited and at least one pairing is asymmetric on shipped data) --
that file is excluded from this task, so the wide 2005-2050 sweep
checks structural invariants only and leaves the citation-chain checks
to the small, individually-audited landmark-year set.

make check (COLITUR_EXHAUSTIVE_SWEEP=1): exit 0, 867 tests, ~316s.
