Class ExportDialogState

src/host/ui/export_dialog.h:42–52

State for the "Export buffer" modal opened from the buffer list's right-click context menu: which buffer to export, the destination path (backing an ImGui InputText, hence the fixed-size buffer), and which BufferExporter::OutputType to write. Owned once by main.cpp and reused across every open/close cycle.
