The inferModuleCallType() function only handled stdlib modules and returned empty types for user-defined modules. This caused type mismatch errors when variables were assigned from user module function calls without explicit type annotations. Now uses GetModuleFunction() to look up user-defined module function signatures and properly infer return types. Fixes #807

Summary
Problem
The
inferModuleCallType()function only handled stdlib modules (std,math,arrays,strings,time) and returned empty types for user-defined modules. This caused type mismatch errors likeexpects u64, got(empty) when variables were assigned from user module function calls without explicit type annotations.Solution
Updated the
defaultcase ininferModuleCallType()to useGetModuleFunction()to look up user-defined module function signatures and properly infer return types.Test plan
