 * [AMENDMENT] This module provides the trace hook functions for FreeRTOS.
 * In the original C, these are macros defined in FreeRTOS.h that default

 *
 * Here we provide them as inline no-op functions. Users can enable tracing
 * by providing their own implementations via a feature flag (TODO).

//! Trace Hooks
//!
//! FreeRTOS provides extensive tracing hooks that are called at key points
//! in the kernel. By default, these are no-ops, but they can be overridden
//! for debugging, profiling, or integration with trace tools like Tracealyzer.
//!
//! ## Categories
//!
//! - `traceENTER_*` / `traceRETURN_*` - Function entry/exit tracing
//! - `traceTASK_*` - Task-related events
//! - `traceQUEUE_*` - Queue operations
//! - `traceTIMER_*` - Timer events
//! - `traceEVENT_GROUP_*` - Event group operations
//! - `traceSTREAM_BUFFER_*` - Stream buffer operations
//!
//! ## Usage
//!
//! These functions are called from kernel code. To implement custom tracing,
//! users would need to provide their own trace.rs implementation (TODO: feature flag).
