Runtime-bound exporter constructors and their configuration contracts.

Exporter pipeline state is private; use lifecycle methods and diagnostic snapshots.

Diagnostic snapshots and their entries can be named through the SDK:

```rust
use nemo_relay::exporter::{ExporterRuntimeDiagnostic, ExporterRuntimeDiagnostics};
use nemo_relay::exporter::otel::OpenTelemetrySubscriber;

fn diagnostics(subscriber: &OpenTelemetrySubscriber) -> ExporterRuntimeDiagnostics {
    subscriber.runtime_diagnostics()
}

fn entries(snapshot: &ExporterRuntimeDiagnostics) -> &[ExporterRuntimeDiagnostic] {
    snapshot.entries()
}
```

```rust
use nemo_relay::exporter::otel::OpenTelemetrySubscriber;
fn pipeline(subscriber: &OpenTelemetrySubscriber) { let _ = &subscriber.inner; }
```

```rust
use nemo_relay::exporter::otel_logs::OpenTelemetryLogSubscriber;
fn pipeline(subscriber: &OpenTelemetryLogSubscriber) { let _ = &subscriber.inner; }
```

```rust
use nemo_relay::exporter::otel_metrics::OpenTelemetryMetricSubscriber;
fn pipeline(subscriber: &OpenTelemetryMetricSubscriber) { let _ = &subscriber.inner; }
```
