MinimapWidget converts absolute graph-space positions into normalised 0..1 coordinates suitable for rendering a miniature overview of the canvas. It also tracks the visible viewport rectangle and handles drag events.

No ImGui dependency — the UI layer calls UpdateNodes(), UpdateViewport(), and GetMinimapNodes() each frame and renders the result using whatever draw calls it likes.

C++14 compliant — no std::optional, structured bindings, std::filesystem.
