+NATS Registration Listener (fox100 + NetBox hostname/action_next lookup + timing + problem counter)
+-------------------------------------------------------------------------------------------
+- One device GET (status + tags + custom_fields.action_next), no duplicate fetch
+- Keeps: nb_problems counter, timings, iface_id diagnostics, same formatting
+- For fox100:
+    * If action_next is empty/absent -> print a simple stdout note and do nothing else
+    * If action_next present and action_last != action_next -> publish task_name=action_next
+      and on success set action_last=action_next and action_next_timestamp=now_epoch
+    * If action_next present and action_last == action_next -> publish only if
+      (now_epoch - action_next_timestamp) >= 600; if timestamp missing/invalid -> allow publish
+      and on success set action_last=action_next and action_next_timestamp=now_epoch
+    * If action_next present -> prepend 3x ASCII BEL to stdout line (kept behavior)

+- One device GET (custom_fields.action_next), no duplicate fetch
+- Keeps: nb_problems counter, timings, iface_id diagnostics, same formatting
+- For fox100:

+      and on success set action_last=action_next and action_next_timestamp=now_epoch
+    * If action_next present and action_last == action_next -> publish only if
+      (now_epoch - action_next_timestamp) >= 600; if timestamp missing/invalid -> allow publish
+      and on success set action_last=action_next and action_next_timestamp=now_epoch
+    * If action_next present -> prepend 3x ASCII BEL to stdout line (kept behavior)
