Migrate trace-forwarder from the deprecated opentelemetry-jaeger exporter to the modern opentelemetry-otlp exporter. This change remediates GHSA-2f9f-gq7v-9h6m (CVE-2026-43868), a medium-severity vulnerability in Apache Thrift. The opentelemetry-jaeger crate is no longer maintained and depends on vulnerable thrift versions (0.13.0 and 0.16.0). The opentelemetry-otlp exporter does not use thrift and is actively maintained. Changes: - Replace opentelemetry-jaeger with opentelemetry-otlp in Cargo.toml - Update tracer.rs to use OTLP exporter instead of Jaeger exporter - Replace --jaeger-host/--jaeger-port flags with --otlp-endpoint flag - Update server.rs to use TracerProvider instead of SpanExporter - Update documentation to reflect OTLP migration - Add examples for common OTLP-compatible collectors Breaking change: Users must update their trace-forwarder invocations to use --otlp-endpoint instead of --jaeger-host and --jaeger-port. Default endpoint: http://localhost:4317 (OTLP gRPC) Generated-by: IBM Bob Signed-off-by: stevenhorsman <steven@uk.ibm.com> Co-authored-by: Hyounggyu Choi <Hyounggyu.Choi@ibm.com>
