Personal node heartbeat probe

Runs on JD-OPS-CENTER and checks one registered node through a private SSH alias. The remote action is fixed and read-only: service state, disk usage and uptime. A JSON receipt is written under /var/lib/guanghu/receipts/ every five minutes.

Real addresses and SSH identity paths belong in /etc/guanghu/nodes/ssh/config on the ops center, never in this repository.

cluster-probe.sh is the six-node generic read-only probe. The systemd instance name is resolved by probe-from-map.sh; callers cannot inject an address, identity path, or arbitrary SSH alias. Each node gets an independent timer and receipt.

enroll-bs-sg-001-from-console.sh is the one-time sovereign-console bridge for the v3.2 Singapore brain. It refuses any other hostname or Gatekeeper node id and installs one source-restricted JD public key. It never accepts a token, address, command, or key from terminal input.
