docs(scope): wire KnotTheory.jl + nextgen-typing into sibling-concerns list

Cross-reference sweep completing the estate rule's 'keep the others updated'
clause: the two final repos (KnotTheory.jl - knot-theory math library / Skein
weak-dep; nextgen-typing - type-theory coordination monorepo) now appear in this
table's sibling-wiring list.
