📝 Walkthrough

Walkthrough

The pull request increases performance benchmark iterations from 1,000 to 10,000 across the benchmark suite and CI workflow, adjusts performance regression thresholds in CI comparisons (50%→25%, 100%→50%, -50%→-25%), and updates documentation accordingly.

Changes

Cohort / File(s)	Summary
Performance Benchmark Configuration .github/workflows/ci-performance.yml, benchmark/performance.js, CONTRIBUTING.md	Increased default benchmark iterations from 1,000 to 10,000; adjusted performance change thresholds in CI workflow comparisons (threshold values halved); removed per-benchmark iteration overrides; updated documentation and PR comment generation to reflect new iteration count and thresholds.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Straightforward numeric constant adjustments with minimal logic density
• Changes are homogeneous and repetitive (all focused on iteration counts and threshold values)
• Configuration and documentation updates with no complex control flow modifications
