ExcelMaster v0.6.40

This release improves advanced VBA automation, restore behavior, support diagnostics, and site embedding protection.

• Advanced VBA preparation is more reliable when generated module specs are involved. Review and run choices now stay aligned with the code that was actually prepared.
• VBA formula-writing guidance is clearer, including escaped quote handling and enabled-mode prompt wording.
• XLSM restore now routes backups by mutation scope, so restore behavior follows the workbook that was actually changed.
• Admin monitoring keeps growth-event client versions, making support diagnostics more accurate.
• The public site now sends CSP and X-Frame-Options headers to deny iframe embedding.

For users, the main impact is steadier macro workflows, safer workbook restore behavior, and better support visibility when diagnosing client-side issues.
