Move the WorkflowVersion wire type and its structural invariants (file
count and size limits, entrypoint presence, unique keys, path
collisions, canonical form) into fabro-types, so fabro-api replaces the
generated schema type without pulling graph parsing or the template
engine into every API consumer. The wire shape is unchanged.
fabro-workflow-version keeps the expensive graph/config/template
validation behind a ValidatedWorkflowVersion newtype and now owns
WorkflowVersionStore: put only accepts validated versions and get still
re-validates blobs read from shared storage. fabro-store goes back to
being domain-agnostic persistence.
Move the static-reference attribute vocabulary (ReferenceKind,
AttributeScope, reference_kind_for_attribute) to fabro_types::graph and
template-syntax validation to fabro-template, so fabro-graphviz no
longer depends on the template engine.
