Subject: [PATCH] fix: support HTTP/HTTPS image URLs in Claude and Gemini
 translators (#344)

Previously only base64 data: URLs were handled in the OpenAI-to-Claude
and OpenAI-to-Gemini request translators. HTTP/HTTPS image URLs were
silently dropped, causing vision-capable models to respond with
"I don't see any image."
