Document the updated Zoom Sequence and Batched Zoom Sequence interfaces, including new `direction`, `amount_type`, `zoom_percentage`, `random_seed`, and `smooth_subpixel` inputs, plus Random easing support.
Clarify how random selection works per execution (and how `random_seed=0` forces fresh rolls) and explain subpixel sampling vs integer crop modes so users can get smoother long/slow zooms and reproducible results when needed.docs(readme): expand zoom node options and random-mode behavior
