style(prune-cache): rewrap the settle-window comment; drop an overclaim

Review nits on #2, both cosmetic. The sentence added last round left its paragraph at 127 characters in a file that otherwise wraps comments at 78-79 — the rewrap after the insert simply did not happen. `awk 'length($0)>80'` over both files now reports one comment line, the pre-existing 93-character usage string at :4. Scenario 14's header called its fixture "the only shape that can tell the two timestamps apart". The property it needs is old mtime with fresh ctime; an old directory renamed a moment ago is the production instance of that, not the only construction of it. "Production's shape" was already carrying the argument. No behaviour change and no assertion change.
