- Add CMake option BUILD_BENCHMARK (default OFF) to build benchmark - Implement ctrack_benchmark with four measurement categories: 1. Accuracy: Measures how accurately CTRACK records function timings 2. Overhead: Compares performance with/without CTRACK enabled 3. Memory: Tracks memory usage per recorded event 4. Calculation time: Measures time to process results - Support configurable event count (default 50M) and thread count - Add baseline recording (--record-baseline) and comparison (--compare-baseline) - Benchmark uses nested functions with predictable timing patterns - Includes multi-threaded stress testing capabilities Usage: ctrack_benchmark [--events N] [--threads N] [--record-baseline] [--compare-baseline] This benchmark will help track performance regressions and improvements across different platforms and CTRACK versions.
- Add comprehensive Developer Guide section to README.md - Document all benchmark features including baseline comparison - Provide best practices for running and interpreting benchmarks - Add CLAUDE.local.md to .gitignore for local documentation

- Implemented tests for summary row validation, including basic and multiple function scenarios. - Added detailed statistics validation tests to ensure accurate tracking of function performance. - Created tests for result meta information and settings filtering to verify correct behavior under various configurations. - Included tests for statistical calculations, including variance, percentiles, and outlier handling. - Ensured consistency across multiple calls and edge cases, such as single executions and extreme values. - Validated statistical stability with large sample sizes and progressive variance analysis.
