Render a screenshot from a signed URL

A signed, embeddable variant of `POST /screenshots` that returns the raw image bytes directly — so a signed URL can be dropped straight into an `<img src>` with **no API key**. PDF output is not supported here; use `POST /screenshots` for PDFs. Authentication is by **signature**, not a Bearer token. The `signature` query parameter is an HMAC-SHA256 of the canonical query string (every parameter except `signature`, sorted by key and joined with `&`), keyed by your organization's signing secret. See [Signed URLs](/docs/guides/screenshots#signed-urls) for how to generate one. Every rendering option from `POST /screenshots` (for example `format`, `fullPage`, `device`, `darkMode`, `cache`) may be passed as a query parameter. Responses set `X-docr-Cache: hit` or `miss` and a one-hour `Cache-Control`.
