This PR adds a new command-line option,
--ignore-missing, to allow the exporter to skip missing constant lookups and proceed gracefully, rather than panicking.By default,
lean4exportstrictly panics when a constant requested for export is not present in the environment. In some systems, it is useful to query multiple declarations without knowing in advance if they are present in the environment.The main motivation for this option is the development of a disproof feature for
comparatorwhere a potentialtarget.disproofdeclaration might be present or not in the submitted solution.
