Ghost — x402 provider decisions

Decides which x402 provider an agent should pay, before it pays. Ranks providers by independent payer activity and returns a USE/WATCH/AVOID decision built from Ghost's own longitudinal record: payer and concentration direction, price and health trends, observed related-party funding, and verdict history — with a fallback and the exact call to make. Paid per call via x402; a free preflight reports whether a decision is even available.
