Python: self.attr(...) on an instance attribute links an unrelated, un-imported module function of the same name #3039

What happens

A call through an instance attribute (self.out = Layer() in __init__, then self.out(x)) links to a module-level function of the same name in a different module. The calling file never imports that module.

# other/features.py
def out(x):
    return x

# lab/model.py
class Layer:
    def __call__(self, x):
        return x


class MLP:
    def __init__(self):
        self.out = Layer()

    def forward(self, x):
        return self.out(x)

• Expected: no edge from MLP.forward to other/features.py: out. Either link to Layer (through __call__) or link nothing.
• Actual on main (60b0d7a): forward calls other/features.py: out, with resolvedBy: exact-match.

Real cases:

• a PyTorch model whose forward calls self.out(...) (an nn.Linear set in __init__) links to a module-level variable out in an unrelated script;
• a test's self.run("git", ...) (bound in setUp) links to a free function run in a harness module the test doesn't import.
