Expand the "Using S3 Directly" section to explain the public dandiarchive S3 bucket layout (blobs/, zarr/, dandisets/), how to browse it through the Quilt web UI, and how to locate a specific asset by reading the contentUrl entries in per-Dandiset assets.yaml / assets.jsonld manifests. Each asset lists both an API download URL (for embargoed data) and a direct anonymous S3 URL. Includes a worked example and notes that DataLad already encodes this Dandiset-to-S3 mapping inside git-annex.

Also drop two stale TODO placeholders in the WebDAV and S3 sections.

Shortcut for review of the added /changed section: https://deploy-preview-239--dandi-docs.netlify.app/user-guide-using/accessing-data/downloading/#using-s3-directly
