Performance Comparison: tsb (TypeScript) vs pandas (Python)

Goal: Systematically benchmark every tsb function against its pandas equivalent, one function per iteration.

Metric: benchmarked_functions (higher is better)
Current best: 539 (Iteration 167)

Steering Issue: #131
State File: perf-comparison.md

Latest iteration (167)
