refactor(cron): rebrand Cron Recipes -> Automation Blueprints

Product rename across every surface: module/file names (blueprint_catalog,
tools/blueprints, blueprint_cmd), slash command /cron-recipe -> /blueprint
(alias /bp), dashboard API /api/cron/blueprints, desktop deep-link
hermes://blueprint/<key>, docs catalog page + extract script, and the
skill frontmatter block metadata.hermes.blueprint. No behavior change.
