Autoloop: perf-comparison

Goal: Benchmark every tsb function vs pandas equivalent.

Current Best Metric: 756 benchmarked function pairs

Program Issue: #221

Latest Iteration (418)

Added firstValidIndex / lastValidIndex benchmarks:

TypeScript: benchmarks/tsb/bench_first_last_valid_index.ts — 100k-row Series with NaN at start, end, and scattered; 500 measured iterations
Python: benchmarks/pandas/bench_first_last_valid_index.py — matching dataset and loop structure using Series.first_valid_index() / Series.last_valid_index()

Metric: 755 → 756 (+1)

🤖 Iteration 420 — ✅ Accepted

Change: Added StringArray extension array benchmarks (bench_string_array.ts / bench_string_array.py)
Metric: 758 (best: 758, delta: +1)
Commit: 8d70dac
Result: Benchmarks cover from/upper/lower/strip/contains/len/fillna on 100k-element arrays with ~10% nulls (50 measured iterations). Python uses pd.array(dtype="string") with equivalent .str accessor methods.
