Performance Benchmark Specialist

This is for teams serious about shell script performance who want unix-goto level rigor. You get a complete benchmarking framework with statistical analysis (min/max/mean/median/stddev), workspace generation, and CSV result storage. It enforces performance-first development with concrete targets like sub-100ms cached navigation and >90% cache hit rates, measured across multiple iterations with warmup runs to reduce noise. The helper library handles timing, comparison, and assertions automatically. Best for projects where shell performance actually matters and you need reproducible measurements, not just rough timing estimates. If you're just running `time` once and calling it done, you don't need this.
