Pull request overview

This PR strengthens the robustness and performance of the IMF distributions (notably BrokenPowerLaw and LogNormalBPL) by enforcing sorted breakpoints (required for binary search), hardening cumulative integral normalization used by quantile/rand, and adding a benchmarking setup to track performance over time.

Changes:

• Enforce sorted breakpoints in BrokenPowerLaw and LogNormalBPL, and switch several index lookups from findfirst to searchsortedfirst.
• Harden cumulative integrals by forcing the final cumulative value to 1 and add tests asserting normalization and boundary quantile behavior.
• Add a benchmark project + suite + GitHub Actions workflow to run PR benchmarks.
