Fixed in de846e431. The array predicates now compare elements with Java's
element contract instead of plain Python membership:
- the builder normalizes a FLOAT array's literals to float32, so
`array_contains('floats', 0.1)` matches a stored `0.1` (float32
`0.10000000149…`) rather than missing it;
- element equality treats NaN as equal to a stored NaN and distinguishes
signed zero (`+0.0` ≠ `-0.0`), mirroring `Double.compare`/`Float.compare`.
Non-float element types keep exact `==` semantics. Added
`ArrayPredicateNumericTest` covering float32 precision, NaN, and signed zero
across `array_contains`; neutralizing either half (literal normalization or the
typed comparison) fails them. flake8 and `git diff --check` clean.
