ERC-8004 registries: profiles, owners, feedback, validations and USDC-weighted trust scores.

Configuration
Development
The remote endpoint is worker/index.ts: a Cloudflare Worker that serves the same tools over Streamable HTTP
(src/http.ts). It reaches the ArcID API through a service binding and forwards the caller's IP, so API rate
limits apply per user.
