fix(0127): namespaced generic calls type their result from the call's bindings

Browse Source 
The plan producer's namespace-fn arms returned the declared return type
without checking type_params, so a qualified generic call's result
carried the unbound T stub: print boxed it as 'T{}', and a non-s64
binding failed LLVM verification (pack monomorphized for the stub,
call returning double). Both fn_ast_map-backed arms now classify
generic callees as generic_fn and infer the return through
inferGenericReturnType, mirroring the bare-identifier path.
