Module setup 

OTLP exporter setup helpers for agent-level telemetry.

Provides a convenience TelemetrySetup builder that configures tracing-subscriber with optional OpenTelemetry exporters. This is a higher-level wrapper around the L0 gemini_genai_rs::telemetry::TelemetryConfig tailored for agent applications.

Feature flags

Console logging (tracing-subscriber with env-filter and fmt layer) is always available. Exporters are opt-in:

• otel-otlp: Adds OTLP trace export via opentelemetry-otlp.
• otel-gcp: Adds Google Cloud Trace export via opentelemetry-gcloud-trace.
