Measure blurb length with wc -w, not estimates

While iterating on a short outreach blurb against a stated length limit, the agent's in-chat estimates were repeatedly low: a version labelled '~98 words' measured 119 with wc -w, about the same as the draft the reader had rejected as too long. Run wc -w on each candidate as soon as a word limit matters, rather than quoting estimates. Also, pbcopy output is lost if a later step, such as copying a link, uses the clipboard, so re-copy the final text at the end.
