chinadaily overseas report writer

generate a client-ready monthly overseas social media monitoring report from one uploaded excel workbook. use when the user uploads a monthly social media operations ledger and wants a complete report, a word report body, or supporting tables for platform performance, account performance, and high-performing posts. follow chinadaily conventions: emphasize international communication insight, include data without dumping raw numbers, avoid claims not supported by the workbook, and default to the structure platform-account-content-cases-issues-recommendations.
