//! Performance tracing for ptop `ComputeBlocks`
//!
//! This module provides lightweight performance tracing compatible with
//! renacer's `BrickTracer` format. It can be used standalone or integrated
//! with renacer for deep syscall-level analysis.
//!
//! **Specification**: SPEC-024 Section 23.5 (Presentar Headless Tracing)
//!
//! # Architecture
//!
//! ```text
//! ┌──────────────────────────────────────────────────────────────────┐
//! │ PerfTrace Architecture │

//! │ └─────────────┘ └─────────────┘ └─────────────────────┘ │

//! ```
//!
//! # Example
//!
//! ```rust,ignore
//! use presentar_terminal::perf_trace::PerfTracer;
//!
//! let mut tracer = PerfTracer::new();
//!
//! // Trace a block of code
//! let result = tracer.trace("collect_metrics", || {
//! app.collect_metrics();
//! });
//!
//! // Get performance summary
//! println!("{}", tracer.summary());
//! ```
