Hot-Swap feature

Building on the Hot-Swap feature introduced in v2.4, NeXdocMan can now fully automate the checking, pulling, and recreation of your Docker containers via system crontab.

New Features:

• Automated Image Updater:
  • Added ENABLE_AUTO_IMAGE_UPDATE to nexdocman.cfg. When enabled, NeXdocMan will silently check for image updates in the background based on your defined IMAGE_UPDATE_CRON schedule.
  • Automatically pulls updates and seamlessly hot-swaps active Compose containers without any user interaction required.
• Intelligent Schedule Management:
  • The -C (or TUI Option 5) command now dynamically syncs both your cleanup and update schedules to the system crontab.
  • 100% Safe: Uses robust strict-matching logic to add, modify, or remove its cron jobs without ever risking duplication or affecting any of your other existing crontab entries.

Documentation:

• The README.md has been updated with a new configuration section detailing the ENABLE_AUTO_IMAGE_UPDATE variables.
