Run any Jamf Pro policy at the next user login or computer reboot

Background
Recently, we had a need to run a particular Jamf Pro policy only the next time the computer rebooted.
Having previously created Recon at Reboot, I started on a modification for this one-off need. About a third of the way into the modifications, a Heaven-inspired question came to mind:
Why don’t you write a script to execute any Jamf Pro policy at the next reboot?
