Implement attribute-based naming schemes for trucks and fires

• trucks will have attribute-based names with IDs, their position coordinates, and for when they're "MOVING", "FIGHTING", "REFILLING".
• via NATS, trucks will broadcast attributes.
• fires will have attribute-based names with IDs, their position coordinates, their intensity, and their calculated urgency.
• via NATS, when a truck detects a fire, it will broadcast attributes of fire.

Acceptance criteria:

• Trucks can discover each other's status via NATS messages.
• Fires are uniquely identifiable beyond just coordinates.
• System logs to the output show attribute broadcasts working.
