Chunk a Transcript for Indexing

Name: NodeTool
Author: NodeTool

Split a long passage into overlapping windows the way a RAG ingest does, then count them. `length` and `overlap` are counted in WORDS, not characters — a 90 here would swallow this whole passage into one chunk. Overlap is the point: a boundary landing mid-sentence loses the claim that straddles it, so neighbouring chunks share a tail. Counting needs Collection first, because Count consumes a stream and a list handed to it arrives as a single item.

The keeper climbed the stair each evening. The lamp needed winding twice a night. By the third winter the mechanism had worn, and the light guttered where it had once held steady. Ships began to pass wider of the point.
