Subject: [PATCH] fix: restore INPUT_IS_LIST and update
 IncrementalVideoStitcher in video.py

Replaces `IncrementalVideoStitcher` with an updated version to fix issue where ComfyUI iterates over string text inputs like the `VHS_FILENAMES` trigger. Adds `INPUT_IS_LIST = True` to the node and unwraps the newly list-wrapped inputs in `stitch_incremental` to process correctly. Ensures `glob` is imported at the module level.
