Give the option to make hook fail if package is present in hook but not any lock files

## What

Give the option to make hook fail if package is present in hook but not any lock files.

## How

Strict option?

## Why

As it is the hook will only give a warning if a package is listed in the hook with but not in any of the provided lock files.

## Details
Hook running result


This was only visible because other packages triggered the hook to fail. If that had not happened the user would not get the warning.

Start at the hook entry point and trace how packages missing from the provided lock files currently produce warnings. Identify how hook options are parsed, then verify that a strict option makes this condition fail while the existing default behavior remains a warning; add or run the relevant hook checks if the repository provides them.
