+    This class implements a singleton pattern to ensure that only one instance
+    of the telemetry system exists, preventing multiple OtelBatchSpanProcessor
+    threads from being created. This is particularly important in environments
+    like FastAPI endpoints where agents are created dynamically, as it prevents
+    resource leaks and excessive thread creation.
+
+    The implementation uses thread-safe double-checked locking to ensure
+    thread safety when multiple threads attempt to create a Telemetry instance
+    simultaneously.
