Detect interfaces per platform; add macOS and single-interface support (closes #2)

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

-## Starlink status
-
-When the non-VPN physical gateway is a Starlink dish, two extra lines appear
-under that pane: dish state, uptime, obstruction and alert count on the first,
-and pop-ping latency and drop rate with downlink/uplink throughput on the
-second. They turn red when the dish is not connected or an alert is active.
-
-Detection is a TCP connect to the dish's fixed local endpoint,
-`192.168.100.1:9200`, made over the physical interface (the same binding the
-latency probes use). The dish sits behind the Starlink router, so this is not a
-gateway-address check. rtnetmon probes once a minute until a dish answers and
-then reads its status every few seconds; when no dish answers, nothing is drawn
-and no status is fetched. The status comes from the dish's local `get_status`
-gRPC call.
