//! Tests for the `pdf_to_images` tool — the on-demand PDF page renderer
//! that lets the agent view figures/screenshots a text-only parse misses.
//!
//! Rendering itself needs a real PDF and a renderer on PATH (covered by
//! `pdf_vision_test`), so these focus on the deterministic contract:
//! schema, the `.pdf`-only guard, and the not-found path.
