Trello card: https://trello.com/c/jPeqHHPu/772-improve-the-observability-of-our-github-workflows

Jobs have no timeout-minutes, so a hung job runs for GitHub's six hour default. This sets one on every job that runs on a runner. Terraform gets 15 minutes and the test job 20. The limits are well above normal run times and only catch hangs.

Jobs that only call a reusable workflow cannot set a timeout; their limits come from forms-deploy. Once govuk-forms/forms-deploy#2332 merges, the shared workflow lint fails any job that has none.

Things to consider when reviewing

• Ensure that you consider the wider context.
• Is it clear what the code is doing?
• Do the commit messages explain why the changes were made?
• Has all relevant documentation been updated?

🟡 Changes recommended

The patch adds only job timeouts and lacks the scheduled, manually dispatchable weekly CI digest workflow promised in the description, so the workflow must be added or the description corrected.
