`nodenv-package` is the corrolary to nodenv-shell, nodenv-local, and nodenv-global. Right now, it is just a subcommand to show the version selected from package.json. In the future, it should also be used to _set_ the version in package.json.
Separately; old code had a bug where the first conditional branch would never be executed (the `get_version_respecting_precedence` function never returned non-zero). This is actually a good thing, because we wouldn't _want_ to print anything to STDERR in this hook, anyway. Also, this hook script is sourced by nodenv so it shouldn't have a shebang, nor be executable. Lastly, we rely on nodenv ensuring each plugin's `bin/` dir is added to PATH so we can just invoke `nodenv-package` directly.
Both the 3rd party deps are symlinked to bin, but we don't actually want to lint them. Meanwhile, the only files that exist in bin that _should_ be linted, are symlinks to libexec. So we can just lint them there.
npm won't include any symlinks in the tarball, so we need to explicitly include the main bin. Pointing to libexec allows npm to make the symlink from node_modules/.bin/ -> libexec/ The other bins aren't necessary because they are provided by npm automaticaly (and included in path that's to npm). (Assuming this is installed globally, which would ensure the bins are in PATH.)
These vars are set by nodenv itself, so they'll likely only be set if the tests were run via nodenv (as is the case with `npm t`). Though other maintainers may have some of these set in the shell profile, so we need to unset them regardless.

Significant refactor to support the traditional subcommand/bin/libexec
structure of nodenv plugins.
plugin_rootfrom bin, so we aren't polluting user's PATH with more stuff.nodenv package-jsonsubcommand. This subcommand presently is a "reader" for package.json just asnodenv localprints the version specified from local.node-versionfile. Intend to have this command also be a "writer" in the future.nodenv-version-fileandnodenv-version-file-read. The benefit is that the origin hook can now print the path to the actual package.json that is affecting the node version, along with the version_spec from said file. It invokes these utilities without needing to source anything.Also addresses some latent bugs:
