The invocation resolver only fired for self/unqualified receivers (Me, the
enclosing type, or a bare name). A call qualified by a type or module name —
Helpers.Log(), the idiomatic way to reach a shared Module Sub — matched
nothing and produced no edge at all, so the caller was disconnected from the
method it invoked.
Map each declared type/module's short name to its owner key, and resolve a
qualified call against the receiver's owner (falling back to raw_calls for
cross-file partial-type merging). A call through a value receiver (a local
variable) still has no known owner and is left unresolved rather than
guessed (fail-closed).
