Changes since 25.09.0:

• Refactor: Move global code into a main function (#464) This is a prequisite for being able to source the script in order to implement unit tests for individual functions.
• Chore: Do not execute any code when forgit is sourced (#464) In order to run unit tests for individual functions we have to be able to source the script without triggering the main execution flow.
• Refactor: extract function to remove status from diff line (#464)
