Class: ArrayBuilder<Z>

Fluent ArrayBuilder: wraps a Zod array schema string and provides chainable methods.

NONEMPTY() TYPE INFERENCE - Version Notes: Both Zod v3 and v4 support .nonempty() with identical validation behavior. However, type inference differs:

.nonempty() infers [T, ...T[]] (tuple-like with at least one element)
.min(1) infers T[] (regular array)

Implementation: ArrayBuilder uses .min(1) instead of .nonempty() for:

Consistency across versions
Clarity in error messages
Alignment with JSON Schema constraints (which don't express tuple constraints)

The validation is functionally identical in both v3 and v4. See ARRAY-NONEMPTY-NOTES.md for details.
