Chat images with no OCR text are now sent to the model as-is

What changed

When an image is attached in Home Chat and addressed to a model without declared image-recognition support, Cherry Studio still runs OCR first — but if OCR finds no text, is not configured, or fails, the image is now forwarded to the provider as a base64-backed native image instead of being replaced with a [could not read this file] note.

Why this matters to the user

Photos, charts, and other images without recognizable text are no longer silently reduced to an unreadable-file note on "non-vision" models. Models whose vision capability is under-declared in their metadata now receive the actual image; providers that truly cannot process images may ignore or reject it according to their own behavior.

What the user should do

Nothing. Images with recognizable text keep the existing OCR-to-text behavior; configuring an image_to_text processor still improves results for text-heavy images on non-vision models.

Notes for release manager

Only the empty-OCR / OCR-unavailable path changed; OCR-with-text, explicit OCR features (translation workflow), and the read_file tool are unchanged.
