* `:uv_version` - select the version of the uv package manager to use.
Defaults to `#{inspect(Pythonx.Uv.default_uv_version())}`.

* `:native_tls` - if true, uses the system's native TLS implementation instead
of vendored rustls. This is useful in corporate environments where the system
certificate store must be used. Defaults to `false`.
