docs(benchmarks): record decimal.js-light comparison

[mstykow]

Summary

• Record a benchmark-grade common comparison for MikeMcl/decimal.js-light at immutable revision b2b0c28e04e4f96d21450d2075ea36064fc9e22d.
• Document matched package, license, copyright, author, email, and file coverage, plus source-backed Provenant advantages in holder and URL extraction.
• Regenerate the benchmark chart and aggregate headline for 255 recorded runs.

Compare artifacts: .provenant/compare-runs/20260909T081928Z-decimal.js-light-13251/

Issues

• Covers: benchmark follow-up to merged PR fix(cli): preserve case-distinct paths-file entries #1431.

Scope and exclusions

• Included: benchmark evidence and generated benchmark documentation.
• Explicit exclusions: no scanner changes were needed because the comparison had zero ScanCode-favored signals.

How to verify

• Run cargo run --manifest-path xtask/Cargo.toml --bin compare-outputs -- --repo-url https://github.com/MikeMcl/decimal.js-light.git --repo-ref b2b0c28e04e4f96d21450d2075ea36064fc9e22d --profile common; confirm 46 common file paths, zero ScanCode-favored signals, and the documented timing/advantages.

Intentional differences from Python

• Provenant reports the two explicit Markdown image targets ScanCode omits, retains a valid repeated decimal.js documentation link, and carries the manifest author into the assembled npm package holder.

Follow-up work

• Created or intentionally deferred: None; the target reached the verification exit condition without scanner changes.

Expected-output fixture changes

• Files changed: None.
• Why the new expected output is correct: No scanner output changed; this PR records the verified comparison and regenerates its chart.

Greptile Summary

Records the benchmark comparison against decimal.js-light at a pinned revision and regenerates the aggregate benchmark presentation.

• Adds the 46-file comparison with machine context, timings, matched outputs, and Provenant-specific advantages.
• Updates the headline statistics from 254 to 255 recorded runs.
• Adds matching Provenant and ScanCode points to the generated SVG chart.

Confidence Score: 5/5

The documentation-only PR appears safe to merge with no actionable correctness or repository-rule issues identified.

The benchmark entry follows the established record format, and its timing data, calculated speedup, chart points, tooltips, ordering, and updated run count are internally consistent.

Important Files Changed
