The D-04 Routstr leg was fallback-only — never user-selectable, and its
Nostr discovery parses a docs-shaped event content ({endpoints, models,
pricing}) that live kind-38421 announcements don't actually carry
({name, about}), so it could never match a real provider. This adds the
explicit path AIUI's model picker needs: /aiui/api/routstr/models
passes through the live aggregator catalog (the instance routstr.com's
own frontend queries; the canonical api.routstr.com 404s), and
/aiui/api/routstr/chat/completions makes one paid, non-streaming,
OpenAI-shaped call — session-gated, egress-screened (S3), refused
without an armed operator budget (D-05), paid via auto_pay_token,
change and refused-request tokens redeemed back into the wallet so a
failed attempt nets zero (verified live: quoted=1 reclaimed=1 net=0).
nginx template gains the location in both server blocks (T-13-15).
