/**
 * Image storage for memory entries.
 *
 * Used by the remember_this tool when the agent passes an image_path: copy
 * the file (compressed if large) into <PI_MIND_DIR>/raw/images/ under a
 * content-addressed name, so two saves of the same image dedup and the
 * image is portable inside the .pi-mind store (the agent's source path is
 * typically transient — /tmp, a session-scoped dir, etc.).
 *
 * No vision / description logic lives here. The agent is responsible for
 * describing the image before calling remember_this, so memory has no
 * dependency on a vision model or any external vision tool.
