Discord's CDN edges occasionally advertise `content-encoding: gzip` (or deflate/brotli) on PNG/JPEG passthroughs while the body is raw, uncompressed image bytes. With the default `reqwest::Client::new()` and the workspace's gzip/deflate/brotli features all enabled, reqwest's transparent-decompression layer chokes on the PNG/JPEG header and returns "error decoding response body" only on `bytes().await` (not on `send()`), causing `download_image_to_blocks` to silently fall back to a text-only block — the user's image never reaches the model. Build the client explicitly with no_gzip/no_deflate/no_brotli so the request advertises identity encoding and the body is read raw. Also set a User-Agent (some CDN edges 403 clients without one) and a 30s timeout aligned with the upstream 5 MB cap. Repro: send an image attachment via Discord; the daemon logs `Failed to read image bytes: error decoding response body` and the turn appends as text-only with `appended_has_image=false`. After this fix the PNG bytes are read and emitted as an Image content block as intended.
