 * Normalize heading numbers:
 * - Chinese ordinals (一、二、) → sequential numbers
 * - Explicit numbers → renumber to sequential (fix out-of-sequence)
 * - Duplicate numbers → fix
 * - Missing trailing dot → add
 * - No number → keep as-is
 *
 * All numbered headings (explicit or Chinese) are renumbered sequentially
 * in document order to ensure globally unique, monotonically increasing numbers.
