Has anyone written (or detected) software/scripts to game the gamification? 24/48h delay/scheduled git push so you can have a healthy work life balance while feigning to employers that you are a code machine.

There is even a tool[1] to draw images in commit history (so called gitifi).

It is possible because git allows to create and push commit with arbitrary date, using GIT_AUTHOR_DATE env variable or --date flag.
