Merge branch 'ef-plan3': Plan 3, the EF resolution engine

Adds the rite-parameterised Precedence resolver, Liturgical_day, Rite,
and Calendar (year as the primitive, because transfers need whole-year
knowledge), the full EF precedence ruleset (RG 91's 28-entry table,
occurrence RG 92-95, commemorations RG 108-111, transfers RG 96-98),
322 bootstrapped sanctoral entries, colitur day <year>, and validation
layers 3-5.

Layer 3 diffs 16801 days against lectio; layer 4 diffs 730 days against
missalemeum; layer 5 pins ~30 dates on the known-tricky years. Both
comparison layers carry cited allow-lists that name the governing RG
paragraph and which engine is right.

The oracle layer earned its place immediately: Holy Thursday was violet
in colitur and lectio alike, because colitur's data was bootstrapped
from lectio and both carried the same error. Only an independent source
could see it. RG 128(b) and RG 122 name it white.

+; A documented one-shot, not part of the build's normal product (spec §4.5):
+; converts lectio's tridentine-calendar.ini into data/ef/sanctoral.sexp. Run
+; via `dune exec tools/bootstrap_sanctoral.exe -- <source.ini> <dest.sexp>`.
+; `unix` is the OCaml distribution's bundled library (already in the switch,
+; not a new opam dependency) -- used only here, never by the kernel, to shell
+; out to `sha256sum` for the provenance header; the kernel itself never reads
+; the environment or a clock.
