// EventViewerMod: Call stack modal renderer.
//
// The main Stack view is a scrolling, time-ordered history. This helper renders a *focused slice*:
// given a selected CallStackEntry, it builds a context vector and renders it in an ImGui modal.
//
// Concepts:
// - "Root" caller: the depth==0 entry that started the call chain. An entry can be its own root.
// - Full context: show all entries produced by the root call chain.
// - Focused context: show the path leading to the selected entry, the entry itself, and then
//   everything that happens underneath that entry.
//
// Note: ImGui modals require calling OpenPopup() on the frame you want the modal to begin opening.
