Follow-up to the getAFlowNode deprecation in the same PR: same AST→legacy-CFG
bridge pattern. The 11 internal call sites (across objects/, types/,
frameworks/, and TypeTrackingImpl) are rewritten to bind a `Return ret`
explicitly, then constrain via `ret.getScope() = f and n.getNode() = ret.getValue()`.
The predicate itself is preserved with a deprecation note so external
users do not experience churn.
Semantic noop.
