Master Edge DEV Contract

The master edge exposes only the DEV acceptance endpoint for this skeleton:

http://74.48.78.17:16667

Health ownership:

hwlab-edge-proxy: accepts public DEV traffic and exposes /health/live.
hwlab-router: owns edge reachability routing and exposes /health/live.
hwlab-tunnel-client: owns D601-to-master frp client status and exposes /health/live.
hwlab-cloud-api: receives proxied API traffic and exposes /health/live.
hwlab-cloud-web: reads cloud APIs only; it does not control hardware.
hwlab-agent-mgr and hwlab-agent-worker: own agent session and worker session health boundaries.
hwlab-gateway-simu, hwlab-box-simu, and hwlab-patch-panel: own DEV simulator and patch-panel health boundaries.

PROD is intentionally gated off for this task.
