Collector now creates a span per event and injects W3C trace context
into JSON records. Ingester extracts that context and creates child
spans, connecting the full event journey: collector -> ingester ->
db.add_log + extract_bounty -> db.add_bounty.
Profiler now creates per-IP spans inside update_profiles with rich
attributes (event_count, is_traversal, bounty_count, command_count).
Traces in Jaeger now show the complete execution map from capture
through ingestion and profiling.
