 """
 NATS Registration Listener (fox100 + NetBox hostname/tag lookup + timing + problem counter)
 -------------------------------------------------------------------------------------------
-Removes duplicate device GET:
+- One device GET (status + tags), no duplicate fetch
-  - Single /devices/{id}/ fetch provides both status and tags.
+- On tag match (and status=active), prepend ASCII BEL to stdout line to alert
-
+- Keeps: nb_problems counter, timings, iface_id diagnostics, same formatting
-Adds/keeps:
-  - nb_problems=<count> prefix on every stdout line
-  - For product=fox100: MAC -> interface -> device lookup in NetBox (urllib only)
-  - Device tag check for slug 'fox100-auto-upgrade-latest' when status=active
-  - If tag present & active: append "action=ok, i'm ready to schedule this device <hostname> upgrade"
-  - Measures per-fox100 NetBox lookup duration (netbox_ms) and total latency (total_ms)
-  - Increments problem counter for NetBox anomalies, includes iface_id where applicable
