218///
219/// This function should be called once before creating any SDK clients.
220/// It initializes the tracing infrastructure for the SDK and optionally
221/// registers a callback to receive log events.
222///
223/// # Parameters
224/// - `callback`: Optional callback to receive SDK log events. Pass `None` to use only platform
225///   loggers (oslog on iOS, logcat on Android).
226/// - `level`: Optional log level. Defaults to `Info` if not specified. Can be overridden by
227///   `RUST_LOG` environment variable at runtime or compile time.
228///
229/// # Example
230/// ```kotlin
231/// // Initialize with callback and trace-level logging before creating clients
232/// initLogger(FlightRecorderCallback(), LogLevel.TRACE)
233/// val client = Client(tokenProvider, settings, ManagedSettingsBindingClient())
234/// ```

236/// # Notes
237/// - This function can only be called once - subsequent calls are ignored
238/// - If not called explicitly, logging is auto-initialized when first client is created
239/// - Platform loggers (oslog/logcat) are always enabled regardless of callback
