feat: add a tool to sync LyoD models from RDF #866

berezovskyi · 2025-12-28T01:49:15Z

I mainly needed such a tool for the SysML/KerML v2 vocab and shape sync/conversion but I think it should be useful for the main project and it is a good place to serve as the tool's home.

In this PR, I ran the sync on:

Core, AM, CM, QM, RM domain vocabs
CM domain shapes

Other changes:

Update the CM shapes domain prefix
Update the CM shapes domain namespace
