How to Determine Which Files Need to Be Updated

Calculate: today's date - last document modification date = days

./tooling/scripts/list-translate-files.sh [days]

Example: today is 2026-01-01, last date is 2025-08-01 → ~153 days

./tooling/scripts/list-translate-files.sh 153

Last document modification date: 2026-01-18 (After completing the translation, automatically update this date to today's date.)
