[geofflamrock]

Fixes an issue where trying to remove a branch when non-interactive would fail by adding options --remove-children and --move-children-to-parent.

Pull Request Overview

This PR adds command-line options to handle child branches when removing a branch in non-interactive mode. Previously, the command would fail in non-interactive scenarios when child branches existed because it couldn't prompt the user for the desired action.

• Added --remove-children and --move-children-to-parent options to the remove branch command
• Updated the command handler to use the provided option instead of prompting when specified
• Added comprehensive test coverage for both new options

This nested ternary operator is difficult to read and maintain. Consider using an if-else statement or extracting this logic into a separate method to improve readability.
