## About the changes
This PR provides a service that allows a scheduled function to run in a
single instance. It's currently not in use but tests show how to wrap a
function to make it single-instance:
65b7080e05/src/lib/features/scheduler/job-service.test.ts (L26-L32)
The key `'test'` is used to identify the group and most likely should
have the same name as the scheduled job.
