Suggestion: add Chronos under Testing & Quality

Hi — suggestion to add Chronos under Testing & Quality.

Chronos is Deterministic Simulation Testing for Node.js and TypeScript: find race conditions and network chaos bugs and replay them bit-for-bit from a single seed. Vitest-native.

Proposed entry:

* [Chronos](https://github.com/sx4im/chronos) - Deterministic Simulation Testing for Node.js and TypeScript (seed-reproducible races and network chaos).

Docs: https://docs-site-chronos.vercel.app/

Happy to open a PR if preferred.
