ponytail-audit

对整个仓库进行过度工程审计，按可删减价值排序建议清单。

全仓库扫描找出过度工程的地方，按能删减或简化带来最大收益排序给出清单。会指出可以直接删掉的死代码、能替换为 stdlib 的自实现或可用平台特性的部分。适合在代码库臃肿、想减依赖或做大范围精简前使用，帮助你优先处理最划算的改动。

findings biggest cut first.

## Tags

Same as ponytail-review:

- `delete:` dead code, unused flexibility, speculative feature. Replacement: nothing.
- `stdlib:` hand-rolled thing the standard library ships. Name the function.
- `native:` dependency or code doing what the platform already does. Name the feature.
- `yagni:` abstraction with one implementation, config nobody sets, layer with one caller.
- `shrink:` same logic, fewer lines. Show the shorter form.

## Hunt

Deps the stdlib or platform already ships, single-implementation interfaces,
factories with one product, wrappers that only delegate, files exporting one
