// `npm info <pkg> --json` (aka `npm view`) behavior:
//
// - Bare package name starts with version string `'latest'`. If
//   `dist-tags['latest']` exists, it's replaced with that value (e.g.
//   `'1.0.0'`). Then ALL versions are filtered through
//   `semver.satisfies(v, version, loose=true)`. When `latest` resolved to
//   an exact version, this is effectively an exact match. When `latest`
//   doesn't exist, the literal string `'latest'` reaches satisfies and
//   matches nothing — zero results, empty stdout.
// - Prereleases are invisible: satisfies runs WITHOUT `includePrerelease`,
//   so no range (not even `*`) matches prerelease versions.
// - When at least one version matches, the JSON output includes a `versions`
//   array with ALL published versions including prereleases (bleeds through
//   from the packument, unfiltered).
// - npmjs.org auto-assigns `latest` on first publish in addition to the
//   provided --tag, so bare queries always work there. GitHub Packages does
//   NOT auto-assign `latest`, so the empty-stdout case above applies.
// - `npm info <pkg>@<exact-prerelease> --json` works as long as that
//   version exists on the registry: exact strings pass `semver.satisfies`,
//   and the output still includes the full `versions` history (same
//   packument merge). Returns empty when the version doesn't exist yet.
// - Consequence: the exact-version fallback only provides data when
//   localVersion is already published. For a new unpublished version both
//   queries return empty → no versions list → only-pre detection is not
//   possible. Such packages (e.g. GitHub Packages with no auto-latest) are
//   published with preState.tag rather than "latest".
