/**
 * Emit CALLS edges for free-call reference sites whose target is
 * imported (or otherwise visible only via post-finalize scope.bindings).
 *
 * The shared `MethodRegistry.lookup` only consults `scope.bindings`
 * (pre-finalize / local-only) for free calls. Cross-file imports land
 * in `indexes.bindings` (post-finalize). Without this fallback, every
 * `from x import f; f()` resolves to "unresolved".
 *
 * **Free-call dedup contract (Contract Invariant I2):** free calls
 * collapse to one CALLS edge per (caller, target) pair regardless of
 * how many call sites the caller contains. Mirrors the legacy DAG's
 * dedup semantics (what the `default-params` / `variadic` / `overload`
 * fixtures expect). Member calls keep position-based dedup elsewhere.
 *
 * Generic; promoted from `languages/python/scope-resolver.ts` per the scope-resolution
 * generalization plan.
