Added — Stable machine identity
- The agent now reports a stable host machine-id (Linux machine-id, via gopsutil's
HostID). The panel uses it to detect when the same physical server has been registered
twice within the same account and shows a "Duplicate" hint. The identifier is only ever
compared within an account — never across accounts.
To apply on an existing install, re-run the installer (curl … | sudo bash) or restart the
service after updating the binary.
