v1.6.5 - Backup reliability fix

What's new in v1.6.5

Bug Fix

• Auto-backup on restart no longer fails with file-lock errors on log files (e.g. R5.log).
  The app now waits for full process exit before starting the backup,
  plus a configurable grace delay (default 3s, adjustable 0-30s in Server Control).

Upgrade

Simply replace the existing exe. No settings migration needed.
