List post engagers

Return the raw list of people who commented on or reacted to a LinkedIn post. READ-ONLY: no campaign, table, or prospect records are created. Works on any publicly-visible post (yours or a competitor's) - LinkedIn surfaces engagement on public posts to anyone with a connected account. Use this when you want to enrich, filter, or qualify the list yourself (e.g. with WebSearch/WebFetch) before pushing a curated subset to a campaign via add-prospects-bulk. For the automated pipeline (scrape → auto-enrich → campaign on a cron), use create-signal-tracker with type=competitor_post_engagers instead.
