GraphComment represents a coloured rectangular annotation that can be overlaid on the graph canvas. CommentManager manages the collection and provides serialisation helpers.

No ImGui dependency — UI code reads the data and draws however it likes.

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