Parsers.jl 3.0 benchmark charts

Grouped-bar charts of Base.parse vs Parsers.parse 2.8.7 (registered release) vs Parsers.parse 3.0 (JuliaData/Parsers.jl PR #210 at e4adc5b), one chart per value family.

Metric: nanoseconds per value — the minimum over BenchmarkTools samples, where each sample parses a seeded 1,000-string corpus of the shape through the public parse(T, ::String) API. Julia 1.12.6, Apple M3 Max, 2026-08-21. results-2x.tsv and results-3.tsv hold the raw measurements (family, shape, contender, ns/value).
