GCS Bucket Discovery Now Available

All service accounts can now list signal bucket names in the delivery project.

gsutil ls -p autobound-signal-delivery

This returns the names of all available signal buckets. Object-level access still requires per-bucket permissions (unchanged). Buckets you aren't licensed for will return 403 on read.

This replaces the previous workflow where you had to check our Delivery docs to find bucket URIs.

Scope: Only bucket names are visible. No object contents, no IAM policies, and no other GCP resources.
