- Topics now default to systant/{hostname}/stats and systant/{hostname}/commands
- Runtime config automatically includes system hostname in topics
- NixOS module defaults use config.networking.hostName
- Supports multiple hosts without topic conflicts
- Environment variables can still override if needed
Example: systant/orion/stats, systant/server2/stats, etc.
