Published crawl budget numbers and honest how-it-works status

Customer-facing crawl budget numbers are now published from data/crawl_budget.yaml on the product page, how-it-works, and standards. Sold API path: 25 routes, 2000 requests, 5 redirect hops, 0.5 s interval, 900 s wall-clock, no separate crawl byte cap, queue depth 4, ownership challenge rate limits 5/host and 20/global per hour. Operator CLI defaults remain 50 routes / 300 s and are labelled as not the sold product.

How-it-works purchase and delivery stages are labelled test mode: order + package code exists with Stripe test keys and manual capture; live checkout stays human-gated. Catalog remains unavailable and unpriced.
