Implement OTEP 4719 to enable sharing of process context information with external readers. This allows services to export resource attributes and metadata via the OTEL_CTX environment mapping without direct instrumentation. The ProcessContextDecorator enriches discovered processes by: - Locating the OTEL_CTX mapping in /proc/<pid>/maps - Reading process context information from remote memory - Merging resource attributes into service metadata This is a proof-of-concept with known limitations: - cilium/ebpf upgraded to v0.21.0 to resolve dependency conflicts - Process context proto definitions pending merge: open-telemetry/opentelemetry-proto#783 - No SDK implementations of OTEP 4719 yet available For testing, use the reference implementation at: https://github.com/open-telemetry/sig-profiling/tree/main/process-context/c-and-cpp See: https://github.com/open-telemetry/opentelemetry-specification/blob/main/oteps/profiles/4719-process-ctx.md Signed-off-by: Florian Lehner <florian.lehner@elastic.co>
