Start automation module

The ability to give Axiom a list of jobs to process automatically would greatly increase the throughput of the system.

Things to consider:
- There should be a list of processing instances
- The automator would assess these instances for those that:

1. Have already run and should be skipped
2. Are currently running
3. Need payloads generated
4. Can be submitted - then actually submit them
5. Have failed - then send an error log to the user

The script would be self-submittable, checking the state of the automation at a frequency determined by the user.

The issue names no files, tests, or entry points. Start by mapping the existing job-processing, payload-generation, submission, and status-reporting paths, then determine how automation state is represented and checked. Done means the module can assess instances, skip or submit them appropriately, report failures, and poll at a user-defined frequency.
