Linux runs exactly as before when both bridge interfaces exist. When they do not, the lone default-route interface is monitored, and a single interface now draws a single UI pane instead of an empty second one. macOS is newly supported: a running VPN tunnel (utun) is monitored as the primary pane alongside the physical default-route interface, or the physical interface alone when no VPN is up. Detection lives in internal/netdetect: interface/route data types, pure selection logic keyed on OS name, and route parsers, all unit-tested on Linux for both platforms. Only the real route query and the per-platform TCP dial binding (source address on Linux, IP_BOUND_IF on macOS) are build-tagged. Ping argument construction is a pure, OS-keyed function. NewMonitor now takes a list of interfaces. Model: opus-4-8
