`let manager = NetworkManager.shared` followed by `manager.fetchData()` on a
later line produced zero call edges. Two gaps: (1) local let/var bindings inside
method bodies were never typed (only class-level properties and function params
populated the per-file type table), and (2) a static-member initializer
(`Type.shared`, a navigation_expression) wasn't recognized as typing the local
even in the class-property path — only constructor calls (`Type()`) were.
Add _swift_local_var_types (mirrors _cpp_local_var_types): walk each function
body and type a local from a constructor OR a `Type.staticProp` access whose head
is upper-cased. `x.method()` then resolves to the receiver type through the
existing single-definition god-node guard. The class-property path also learns
the Type.shared shape. Reported on a 23k-file iOS corpus where this idiom is the
median call pattern.
Verified: the repro resolves (loadIfNeeded -> fetchData/isLoading); constructor
locals still resolve; a lowercase-head init (`other.child`) does NOT falsely
type; and an ambiguous method name resolves to the receiver-typed class only.
Swift + full suite 2789 passed.
