R2 Outage Toggle

Modifies s3_management/manage_v2.py to disable or re-enable Cloudflare R2 (download-r2.pytorch.org) URL generation for PyTorch foundation packages. Use during R2 outages to fall back to S3/CloudFront, or to restore R2 usage after an outage is resolved.

When to use this skill

Use when the user asks to:

• Disable R2 / turn off R2 / stop using download-r2.pytorch.org
• Re-enable R2 / turn on R2 / restore R2 usage
• Handle an R2 outage or Cloudflare outage
• Switch nightly or prod packages away from R2
• Fall back to S3/CloudFront for foundation packages
