* The root process generates a UUID-based ID and exports it via the

* LOGOS_INSTANCE_ID environment variable. Child processes inherit the variable
|
|
* and return the same ID, so all processes in the application tree share one
|
|
* ID. Used by both provider and consumer to build matching registry URLs.
