Full implementation of the nginx dynamic module with: - SO_BINDTODEVICE-based per-interface traffic attribution - Per-worker lock-free counters flushed to shared memory - Prometheus text and JSON scrape endpoint at configurable location - UDP-only global logtail (ipng_stats_logtail) for fire-and-forget access log streaming - $ipng_source_tag nginx variable for use in log_format/map - Histogram buckets, EWMA rate gauges, zone meta-metrics - Debian packaging (libnginx-mod-http-ipng-stats) - Robot Framework end-to-end tests via containerlab - SPDX Apache-2.0 headers on all source files
