Create a portable bash shell script to safely uninstall the Fabric AI CLI and related packages on Debian, Ubuntu, and Fedora systems. The script must:

- Detect the operating system and select the appropriate package manager (`apt`, `dnf`, or `yum`).
- Uninstall Fabric packages installed via system package managers and Python package managers (`pip`, `pip3`).
- Check for errors after each removal step; abort the script if a critical error occurs.
- Prompt the user for confirmation before making any changes.
- Advise the user to reboot the system if required after uninstallation.
- Log all actions and errors to a user-specified log file.
- Be fully self-contained and compatible with bash.

Reference the official [Fabric documentation](https://github.com/danielmiessler/Fabric) and your distribution’s package manager documentation for implementation details.
