chore(viewer): add dev:live:token convenience script with baked-in dev token

Adds an optional script for quick local LAN testing without having to set
RECORDING_VIEWER_TOKEN manually. Token value is intentionally noisy
('dev-only-do-not-use-in-prod') and the README warns it must not be used
for studies or public networks. dev:live (env-var required) is unchanged.

+#### Quick local testing
+
+For fast iteration on the same network without picking a token, use the
+convenience script with a baked-in token:
+
+```bash
+npm run dev:live:token   # token = dev-only-do-not-use-in-prod
+```
+
+Do NOT use this in a real study or on a shared/public network. The token is in
+the repo, so anyone with source access knows it. Use `dev:live` with a real
+random token for anything that matters.
+
 ### Connect (observer laptop)
 
 Open `http://<recording-laptop-IP>:5173` in any browser. Enter the token.
