- Implement computeCounterDelta for Counter32/Counter64 with wraparound handling
- Sanity threshold discards deltas > 90% of max value (device reset detection)
- CounterCache uses Redis MGET/MSET pipelining for efficient state persistence
- Counter keys use "snmp:counter:{device_id}:{oid}" format with 600s TTL
- Add SNMPMetricsEvent and SNMPMetricEntry structs to bus package
- Add PublishSNMPMetrics publishing to "device.metrics.snmp_custom.{device_id}"
- Full test coverage: 10 counter tests including miniredis integration

- DeviceInterfaceEvent type publishes to device.interfaces.{device_id}
- PublishDeviceInterfaces method follows existing publisher pattern
- DEVICE_EVENTS stream includes device.interfaces.> subject
- PollDevice collects interface info after traffic counters, before health
- Non-fatal errors with Prometheus metrics for publish success/failure

- RFMonitorStats struct for per-interface RF data (noise floor, channel width, TX power)
- CollectRFMonitor with v6/v7 RouterOS version routing
- WIRELESS_REGISTRATIONS NATS stream with 30-day retention (separate from DEVICE_EVENTS)
- WirelessRegistrationEvent type and PublishWirelessRegistrations method
- Poll cycle collects per-client registrations and RF stats, publishes combined event

Without a byte limit, the stream grows unbounded within its 24h
max_age window. At 101 devices polling every 60s, it hits 128MB
in ~10 hours and OOMs the NATS container.

Poller publishes session end events via JetStream when SSH sessions
close (normal disconnect or idle timeout). Backend subscribes with a
durable consumer and writes ssh_session_end audit log entries with
duration.
