Prevent outdated pull request dashboard runs from publishing

[trask]

Prevent queued pull request dashboard jobs running older code from publishing after a newer dashboard version has taken over. Each target repository records the dashboard state and rendering versions used by the active publisher. A job with older or unrecognized versions exits before posting status comments, reminders, review requests, Slack notifications, or the dashboard issue; current jobs continue normally.

The guard derives its compatibility marker from the dashboard’s existing state and renderer version constants, so bumping one automatically fences older queued jobs without treating unrelated shared-workflows commits as dashboard releases.

• The revision check runs only in publish-dashboard, after update-dashboard has already executed dashboard.py and pushed to the same state branch (workflow lines 118–154). A queued lower-revision worker can therefore see a newer state schema as mismatched, regenerate it using old defaults, and commit that downgrade before being skipped here, potentially discarding dashboard state. The revision must also be claimed/checked inside the dashboard-update CAS transactions so stale updaters exit without writing state.
