npm's `min-release-age` config has type `[null, Number]`. The value `3d`
parses to NaN, which propagates into `before = new Date(NaN)` (Invalid
Date). Pacote then calls `.toISOString()` on it and throws
`RangeError: Invalid time value`, breaking every local `npm install`.
Drop the `d` suffix in all six `.npmrc` files. The `<days>` in npm's
type hint is a label, not part of the value.
This is a no-op for CI (`npm ci` ignores this setting per the comment
in the file) but unblocks local `npm install`.
