ebeea9da - router: send the input as chunks to the backend

router: send the input as chunks to the backend Before this change, the generation input was sent to the backend as a single string, encoding images as Base64 and packing them in Markdown-style links. This change adds a new chunked input representation that separates text chunks from images chunks. Image chunks contain binary data (for smaller message sizes) and the image's MIME type. The stringly-typed inputs are still sent to support backends that do not support chunked inputs yet.
