/**
 * * Compare two strings using natural sorting (e.g., "file2" < "file10").
 * Optionally supports case-insensitive and locale-aware string chunk comparisons.
 *
 * @param a - The first string to compare.
 * @param b - The second string to compare.
 * @param options - Optional settings to configure comparison behavior.
 * @param options.caseInsensitive - If true, compares string chunks without case sensitivity. Defaults to `true`.
 * @param options.localeAware - If true, uses localeCompare for string chunk comparisons. Defaults to `false`.
 * @returns A negative number if `a` comes before `b`, a positive number if `a` comes after `b`, or 0 if equal.
