feat(openclaw): persist config as ~/.openclaw/openclaw.json

- Read gateway token/port via JSON.parse (same structure as former YAML)
- Update claw.cutos.ai origin by replacing URLs in JSON string fields
- Export resolveOpenclawConfigFile() for frpc + client
- Drop js-yaml dependency
- install: ExecStartPre touches openvfd only if nodes exist (3528-friendly)
- Add tools/deploy-rsync.sh for syncing /opt/clawd over SSH
