/**
 * @file driver_log_sink.cpp
 * @brief Implementation of DriverLogSink (LIB-04 / D-19).
 *
 * Adapts SafeDriverLog (driver/src/driver_log.hpp) to the ILogSink shape
 * so the same MultiSinkLogger fan-out used by the client also drives
 * vr::VRDriverLog()->Log() output into vrserver.txt. SafeDriverLog
 * already handles the pre-VR_INIT_SERVER_DRIVER_CONTEXT case by falling
 * through to stderr (driver_log.hpp:39 Rule-3 guard from P6).
 *
 * Driver-side composition root wiring (DriverLogSink + FileLogSink under
 * DeviceProvider::Init) lands in 08-02 — bundling here would force this
 * plan to also evolve device_provider.cpp ctor signature.
