benchmarking

All benchmarks live in the bench/ directory at the repository root:

Each file should focus on a single benchmark comparing multiple implementations (e.g., @latest vs @workspace).

Benchmarks use cronometro, which runs each test in an isolated worker thread for accurate measurement.

在为 Jazz 包编写或运行性能基准测试时使用此技能。涵盖 cronometro 设置、文件约定、工作线程的陷阱以及如何比较实现。 来源：garden-co/jazz。
