Adds a check within the `PipeHook` to ensure the number of input streams
provided to a `pipe` operation matches the number of parameters expected
by the associated lambda function. This prevents runtime errors and
provides a clearer compile-time diagnostic.
Additionally, this commit corrects the order in which a `CallFrame` is
pushed onto the VM's frame stack. By pushing the frame earlier, it
ensures that slow-path `unpack` operations have access to a valid frame,
preventing "No call frame" errors.
