Stacked on Persist and restore workspace-scoped ACP sessions (#136). Adds native PNG/JPEG/WebP prompt images when the selected model advertises vision, plus embedded text and binary context. Binary inputs are validated and stored by content hash for future turns; images use Penguin's existing image_paths path. Embedded text is labeled untrusted context, binaries remain inert references, and no remote resource is automatically fetched.

Limits: 10 MiB per binary, 20 MiB aggregate attachments, 40 million image pixels. Invalid base64, mismatched media type, invalid image data and unsafe asset destinations fail before model execution. Attachments remain in native session storage after closing a session for continuation. This does not add audio or media conversion.

Validation: 35 aggregate ACP tests pass, including image data preservation, native model input, invalid/oversize inputs, embedded text/binary, and subprocess wire embedded context. Scoped Ruff and diff checks pass. Live provider/editor still not claimed.
