Subject: [PATCH] Drop AWS S3 release upload, keep only Cloudflare R2 (#1092)

The release pipeline uploaded artifacts to both AWS S3 (goreleaser `blobs:`) and Cloudflare R2 (custom publisher) during the migration period. The migration is done, so this removes the S3 half:

- drop the `blobs:` block from `.goreleaser.yaml`
- drop the `AWS_*` / `S3_*` env from the nightly and tag release workflows
- update the comments in `.goreleaser.yaml` and `scripts/upload-r2.sh` accordingly

Cloudflare R2 upload (including the early `--check-config` preflight step) is unchanged, and the `AWS_*` repo secrets are no longer used.
