Load the in-repo fixtures once and feed the decoded cases straight into
the parameterized test, instead of collecting IDs and re-reading every
file to find the matching case per ID. PredicateConformanceFixtureCase
gains Identifiable + Sendable (for the arguments) and a
CustomTestStringConvertible extension so each case still displays by id.

Asserting an exact warning count coupled the fixtures to engine
internals. Match warnings by substring only (count-agnostic); an empty
`contains` now asserts that no warning is emitted, preserving the
"does not warn" cases. The three count-only fixtures gain the
"missing variable" substring they actually emit.

Drop the khepri single-file plumbing (defaultFixtureURL, fixtureURL,
the no-arg loadCases(), the env var, and the unused fixtureNotFound
error). This PR only runs the in-repo PredicateFixtures/ directory; the
khepri conformance loader lands with its test in the conformance PR.

Implements the json-logic-js some/all iteration predicates. Operator coverage
is expressed as JSON predicate fixtures (some.json / all.json) run by the
shared fixture runner introduced downstack, replacing hand-written unit tests.

Implements the json-logic-js min/max operators (variadic flat list, ±∞ for
empty input, NaN propagation for non-numeric operands). Coverage is expressed
as JSON predicate fixtures (min.json / max.json) run by the shared fixture
runner, replacing hand-written unit tests.

Completes the json-logic-js iteration family (none/map/filter/reduce) on top
of some/all. Coverage is expressed as JSON predicate fixtures
(none.json / map.json / filter.json / reduce.json) run by the shared fixture
runner, replacing hand-written unit tests.

Expresses the "empty-string key resolves to the whole scope and is not
missing" case as a `{"!!":{"missing":[""]}}` -> false fixture; the string
coercion the other missing fixtures use can't distinguish [] from [""].
Bumps the pinned fixture count to 237. Keeps the corpus in sync with the
purchases-android counterpart.

Adds fixtures for the empty-segment dot-path splits, var default-vs-null-leaf
behavior, and the non-numeric missing_some threshold (7 new cases), bumping
the pinned count to 244. Also adds the var-null-path Swift test so the
non-fixturizable cases match the purchases-android counterpart. Keeps the
fixture corpus byte-identical across both repos.

Remove the duplicate WorkflowsCacheTests.swift PBXFileReference introduced
during a merge, and add a dedicated "Min and max" grouping comment so the
min/max cases are no longer lumped under arithmetic.

Cover logging ±Infinity, NaN, empty object, and empty array. Empty
array and empty args were indistinguishable under substring matching
(they log "" and "null"), so `expectedLogs` now asserts the exact,
ordered list of emitted messages. `expectedWarnings` is unchanged.

The tag was always the single `[RulesEngine]` constant and never varied
at any call site, so it added protocol surface without flexibility. For
the `log` channel a prefix also defeats the verbatim passthrough. Hosts
that bridge the logger prepend their own identifier when they need one.

Wrap NaN- and infinity-producing subexpressions in `log` and assert the
exact emitted string via `expectedLogs`, so these fixtures verify the
intermediate value, not just the final truthiness. Covers arithmetic,
min, max, reduce, missing_some, and evaluator edge cases.
