Summary of Changes

Hello @doublegate, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request centralizes and applies multiple pending dependency updates, primarily focusing on the rand Rust crate and various GitHub Actions. The goal is to modernize the project's dependencies, enhance security by updating the rand crate, and ensure compatibility with newer environments like Node.js 24 for GitHub Actions, all while reducing the overhead of managing individual Dependabot PRs.

Highlights

• Dependency Consolidation: Consolidated six separate Dependabot pull requests into this single, tested update, streamlining the dependency management process.
• Rand Crate Update: Updated the rand crate from version 0.8.5 to 0.9.2, bringing security improvements (removed zerocopy dependency) and requiring API changes.
• Rand API Migration: Migrated rand API calls, specifically thread_rng() to rng() and gen_range() to random_range(), and updated trait imports from SliceRandom to IndexedRandom via rand::prelude::*.
• GitHub Actions Upgrade: Upgraded several GitHub Actions to their latest major versions (e.g., actions/checkout from v4 to v6, actions/upload-artifact from v4 to v6), ensuring Node.js 24 compatibility and a minimum Actions Runner version of v2.327.1.

Code Review

This pull request is a great consolidation of multiple dependency updates, including a major update for the rand crate and several GitHub Actions. The code changes correctly migrate to the new rand v0.9 API for the most part. My review includes a couple of suggestions to replace the use of an unstable rand API function with its stable (though deprecated) predecessor to improve long-term stability.

[Copilot]

The PR description states "All GitHub Actions updates are Node.js 24 compatible", but softprops/action-gh-release@v2 actually uses Node.js 20, not Node.js 24. While this doesn't affect functionality (both are supported by runner v2.327.1), the description should be corrected for accuracy. Consider changing it to "All GitHub Actions updates are compatible with Node.js 20+ and minimum runner v2.327.1" or similar.
