README patch note (Jobs Apps Script)

If you want to mention the Apps Script in the repo README without rewriting the whole file, you can add a small note near the jobs data section.

Suggested text:

• data/jobs.json
  • Generated from a Google Sheet.
  • The sheet uses a Google Apps Script layer to approve/reject submissions (Status dropdown) and to copy approved rows into For Show.
  • Maintainer doc: docs/jobs-pipeline.md
