mind-body: a delivered chat image reaches her session as an image block
ChatDelivery gains tuple index 11, `image: Option<ChatImage>` ([path, mime, size, sha256], a reference into her per-room image store, never bytes); the pending kind is gamecult.persona.chat_pending.v2, and v1 answers and records still decode with no image. chat_image::load is the one place a reference becomes bytes: exact `<hex sha256 of room id>/<sha256>[.ext]` path with no traversal or symlink, regular file, 5 MiB declared and actual, declared size and sha256, png/jpeg/gif/webp magic bytes matching the declared mime. The persona line carries the image as a base64 image block after its text and an `attachment role=organ` line saying attached or not shown and why. The stream-json echo of a line with blocks still counts as our echo. The store is MIND_PERSONA_IMAGE_STORE; unset, every image is not shown. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
