//! Array operators: filter / map / reduce / merge / quantifiers / sort /
//! slice / length.
//!
//! # File map
//!
//! - [`filter`] — `filter` (predicate-based array selection).
//! - [`map`] — `map` (per-element transformation).
//! - [`merge`] — `merge` (variadic array concatenation, flattening one level).
//! - [`quantifiers`] — `all`, `some`, `none` (predicate scan with short-circuit).
//! - [`reduce`] — `reduce` (fold over an array with `accumulator` / `current` slots).
//! - [`length`] — `length` of strings/arrays (gated on `feature = "ext-string"`).
//! - [`slice`] — Python-style `slice` (gated on `feature = "ext-array"`).
//! - [`sort`] — `sort` (key-based ordering, gated on `feature = "ext-array"`).
//! - [`helpers`] — shared infrastructure: `IterSrc`, `ResolvedInput`,
//!   `resolve_iter_input` (used by every iterator op), `FastPredicate`
//!   (filter / quantifier fast paths), and a few small comparison helpers.
