- scripts/deploy-cvm.sh: backup remote server.ts -> upload -> restart -> confirm
the heartbeat, with --rollback. Host/SSH values come from the never-committed
~/.config/skatespots/cvm.env (or CVM_HOST), so no host details ever enter this
public repo.
- package.json: add `npm run deploy:cvm`.
- AGENTS.md: record that the CVM server runs on ONE external host (deploy via
deploy:cvm) and that the discovery relay, not the server, is the SPOF.
