+/// Enumerates currently active Windows audio endpoints, separately for output (render — used
+/// for loopback capture) and input (capture — mics, line-ins) devices. Used by the App to
+/// populate the two send-device check-lists.
+///
+/// Selection state is intentionally NOT persisted: every session starts with all checkboxes
+/// unticked and nothing being sent. The user re-ticks once per session. Stops the
+/// "wrong-device-still-checked" surprise after a card unplug, ID change, etc.
