 * Comparator for distinctUntilChanged on the filter values stream.
 * Emits only when:
 *  - Array length changes, or
 *  - A primitive value at some index changes, or
 *  - Any element is non-primitive (object / function / array) -> always treated as changed.
 *
 * Rationale:
 * Objects/arrays are assumed to have unstable identity/content; any occurrence triggers a new emission.
 *
 * @param prev Previous emitted array of active filter values.
 * @param curr Current emitted array of active filter values.
 * @returns true if both arrays should be considered equal (no new emission), false otherwise.
