[FEATURE]: Add RapidOCR-json support — reading image text into the model when it can't see imagesI come from CHINA! I solution OPENCODE'S EYE problem, you can use RapidOCR-json, let bigpickle model (LLM) takes the picture's words!!

Problem

OpenCode refuses images for models that don't support image input, e.g. "Cannot read image.png ... this model does not support image input". Users who rely on text-only LLMs (like bigpickle) can't share screenshots of errors, logs, or documents.

Proposed solution

Integrate the local, offline RapidOCR-json engine as an optional image-to-text step:

• When a user attaches an image and the active model doesn't accept vision, run RapidOCR-json locally to extract the text.
• Replace the image part with that extracted text before sending to the model, so text-only models can still read image content.
• Fall back gracefully if no OCR engine is installed or recognition fails (vision models keep receiving the image unchanged).

Expected behavior

A user can paste a screenshot and, on a non-vision model, receive a reply based on the text read from the image — with no network and no image data sent to the provider.

Environment

• Windows, OCR engine: RapidOCR-json (offline, RapidOcrOnnx based)
• Region/backends: local text-only LLM (bigpickle)words!!
