+feat(OtlpExporter): expose internal OTLP exporter as public API
+
+The internal OTLP exporter is now available as `OtlpExporter.make()`. This allows building custom multi-endpoint tracers or composing multiple exporters without copying internal code.
+
+Example:
+```typescript
+import { OtlpExporter } from "@effect/opentelemetry"
+
+const exporter = yield* OtlpExporter.make({
+  url: "https://api.honeycomb.io/v1/traces",
+  headers: { "x-honeycomb-team": "api-key" },
+  label: "honeycomb",
+  exportInterval: "5 seconds",
+  maxBatchSize: 100,
+  body: (spans) => ({ resourceSpans: [{ scopeSpans: [{ spans }] }] }),
+  shutdownTimeout: "3 seconds"
+})
+
+exporter.push(spanData)
+```

+/**
+ * OTLP Exporter
+ *
+ * A generic OTLP exporter that can be used to build custom tracers, metrics exporters,
+ * or loggers that send data to OTLP-compatible backends.
+ *
+ * This exporter handles:
+ * - Batching of data with configurable batch size
+ * - Automatic retry with backoff on transient errors
+ * - Rate limiting with 429 Retry-After header support
+ * - Graceful shutdown with timeout
+ * - Automatic disabling for 60 seconds on persistent failures
+ *
+ * @since 1.0.0
+ * @example
+ * ```typescript
+ * import { OtlpExporter } from "@effect/opentelemetry"
+ * import { BunHttpClient } from "@effect/platform-bun"
+ * import { Effect, Layer } from "effect"
+ *
+ * const program = Effect.gen(function*() {
+ *   const exporter = yield* OtlpExporter.make({
+ *     url: "https://api.honeycomb.io/v1/traces",
+ *     headers: { "x-honeycomb-team": "your-api-key" },
+ *     label: "honeycomb",
+ *     exportInterval: "5 seconds",
+ *     maxBatchSize: 100,
+ *     body: (spans) => ({ resourceSpans: [{ scopeSpans: [{ spans }] }] }),
+ *     shutdownTimeout: "3 seconds"
+ *   })
+ *
+ *   // Push data to be exported
+ *   exporter.push({ traceId: "...", spanId: "...", name: "my-span" })
+ * })
+ *
+ * program.pipe(
+ *   Effect.scoped,
+ *   Effect.provide(BunHttpClient.layer),
+ *   Effect.runPromise
+ * )
