Added a test suite under addons/otel/test/ for the OpenTelemetry filter. Five scenarios exercise different filter capabilities: standalone (sa) covers all hook points including idle-timeout heartbeats, metrics and log records; compact (cmp) covers the full request/response lifecycle with ACL-based error handling; context (ctx) tests explicit inject/extract propagation through numbered context variables; frontend/backend (fe/be) tests distributed tracing across two HAProxy instances; and empty tests bare filter initialisation with no active scopes. A performance benchmarking script (test-speed.sh) uses wrk to measure throughput and latency at different rate-limit settings (100% through 0%, disabled, and filter-off). Each scenario includes comprehensive YAML exporter definitions covering OTLP file/gRPC/HTTP, ostream, memory, Zipkin, and Elasticsearch backends.
