Move validation/lint framework and all 24 rules into a dedicated
fabro-validate crate. As prerequisites, move Fidelity, stylesheet
parser/types, and condition parser into fabro-graphviz (where the
Graph types they operate on already live) so fabro-validate can
depend on fabro-graphviz directly without a circular dependency.

Move the self-contained graph/ and parser/ modules into a new
fabro-graphviz crate so the Graphviz DOT parser can be used without
pulling in the full workflow engine.
