CI Scheduled fork upstream ensurance

[Ardakilic]

Problem

Forks of this repository inherit the same GitHub Actions workflows, including the hourly cron schedule on sync-models.yml. Every hour, each fork (currently 1k forks available) spins up runners and attempts to run the full model sync pipeline: A massive and unnecessary waste of CI resources, with missing CI secrets. It currently generates a ton of failing pipelines for every fork.

Every person who forked the repository will start to get hourly failing CI notification and mail as well, due to missing repository secrets.

People could go into their fork's Settings → Actions and disable them, but nobody does.

Changes

Added if: github.repository == 'anomalyco/models.dev' to:

• .github/workflows/sync-models.yml — both providers and sync jobs (scheduled cron, the main offender)
• .github/workflows/deploy.yml — the deploy job (push-triggered, but also runs on rebases/force-pushes to dev in forks, wasting runners)

This ensures these workflows only execute on the upstream repository.

Reasoning

• Prevent recurring Action runs on every fork
• Reduce wasted GitHub Actions minutes across the ecosystem
• Eliminate hourly failing CI notifications for fork maintainers
• More polite to the community members who fork the repo
