Prism Launch Echo API
Scrape Prism Launch Echo data with one API call. Runs a Hacker News search, digs the top threads' comments, and pulls the dev-blog web echo (content_analysis), with an optional GitHub repo/dossier (explicit `repo=` or auto-resolved from the HN/web hits), folded into a launch-reception snapshot with computed attention + echo + a methodology_version. Comment legs are the coverage spine (<0.5 → 50% refund); a dead HN search → full refund.
