--native-tls
Whether to load TLS certificates from the platform's native certificate store.
By default, `uv` loads certificates from the bundled `webpki-roots` crate. The
`webpki-roots` are a reliable set of trust roots from Mozilla, and including them in `uv`
improves portability and performance (especially on macOS).
However, in some cases, you may want to use the platform's native certificate store,
especially if you're relying on a corporate trust root (e.g., for a mandatory proxy)
that's included in your system's certificate store.
