Timing to be reconsidered after Fed-A meeting in 2025-02-10

LinkML generation to SHACL is not sufficient for SHACL (see https://github.com/linkml/linkml/issues?q=is%3Aissue%20state%3Aopen%20label%3Agenerator-shacl which @elichad looked) so this will have to be done by copy-paste instead from existing runcrate profiles.

@elichad to contribute SHACL expertise.
