Argent React Native Profiler

Profiles React Native apps running on Hermes to catch render bottlenecks and CPU hotspots. Starts both React and native profilers in parallel, captures commit trees with timing data, then ranks components by render cost. The workflow pushes you to drill down with query tools (call trees, commit cascades, hang stacks) rather than stop at surface metrics. What stands out is the emphasis on re-profiling after fixes to actually measure whether your change improved anything, regressed something else, or did nothing at all. Works alongside flow recording so you can replay the exact same interaction sequence for honest before and after comparisons.
