Subject: [PATCH] fix: strip only internal prefix from model name for
 compatible providers (#243)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Changed model.split('/').pop() to model.split('/').slice(1).join('/')
- Preserves vendor namespace in model names (e.g. moonshotai/Kimi-K2-Instruct)
- Also fixes multimodal image_url → input_image conversion for Responses API (#242)
- image_url parts from Chat Completions are now properly converted to input_image format
