Subject: [PATCH] Use CDN URL for public file links when S3_CDN_URL is set
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

getPublicUrl returns the CDN URL (files.second-brain.ru via Bunny) when
S3_CDN_URL is configured, falling back to the direct S3 endpoint. This
was a manual patch on the build server that was never committed —
restore it so new uploads also get CDN-backed (RU-accessible) URLs.
