Steps to reproduce:

> aube config set minimum-release-age 2880
set minimum-release-age=1440 (C:\Users\iki\.npmrc)

> npm config list
npm warn Unknown user config "minimum-release-age". This will stop working in the next major version of npm. See `npm help npmrc` for supported config options.

Some solution options:

1. Mise-like: ~/.config/aube/config.toml + optionally use ~/.npmrc for auth/registry

2. pnpm<=10: ~/.auberc (~ for simplicity, pnpm has more elaborate platform dependent config directory) + ~/.npmrc for auth/registry

3. pnpm>=11: similar to 1, but uses own yaml + rc and does not use ~/.npmrc at all

IMO 1 seems best, mise approach ftw :)
