Implement list.__setitem__(slice) with full support for step=1 (same size, grow, shrink) and extended slices (step != 1). First test covers same-size replacement: lst[1:3] = [10, 20]. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

lst[1:2] = [10, 20, 30] - replacement longer than slice. Already passes with existing implementation. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
lst[1:4] = [10] - replacement shorter than slice. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
lst[1:3] = [] - assign empty list to delete elements. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
lst[1:1] = [10, 20] - insert without removing. Fixed bug where s.indices() was called with slice_len instead of ll.length, causing wrong start position for empty slices. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
lst[::2] = [10, 20, 30] with matching size, raises ValueError on mismatched size. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
