Macro nros_platform_export_log

    ($ty:ty) => { ... };
}

Phase 88.11 — emit nros_platform_log_write + nros_platform_log_flush from a PlatformLog-implementing ZST. Use this on bare-metal / custom platforms (mps2-an385, stm32f4, esp32-baremetal, …) that don’t ship a separate C implementation file. The implementor’s write receives the rendered body + logger name as &[u8] slices.
