feat(macos-rssi-bridge): add `make start` one-shot orchestration

`make start` builds both binaries, launches the v2 sensing-server and the
bridge under a single process group, opens both UIs (sensing UI on :8080
and the tomography dashboard on :9090/dashboard), and tears both down
cleanly on Ctrl-C via a TRAP. Adds `make stop` for stray-process cleanup
and `make build-server` so the sensing-server build can be invoked
independently. README updated to point at the one-command flow.

 ## Run
 
+One command — builds both, launches the sensing-server and the bridge,
+opens both UIs, and cleans up on Ctrl-C:
+
+```bash
+make start           # → sensing-server (:8080) + bridge (:9090/dashboard)
+make stop            # kill any leftover sensing-server / bridge process
+```
+
+Or run them manually in two terminals if you want to see logs side-by-side.
 In one terminal, the sensing-server (provides UI + UDP receiver):
