/**
 * /.well-known/oauth-authorization-server — RFC 8414 Authorization Server Metadata
 *
 * Required by Anthropic Claude.ai connectors and by any spec-compliant
 * OAuth 2.1 client doing discovery. Without this endpoint the client cannot
 * find the authorization, token or registration URLs without being
 * pre-configured — which Anthropic's connector flow does not do.
 *
 * Spec: https://datatracker.ietf.org/doc/html/rfc8414
 *
 * The base URL of every advertised endpoint is request-derived (lib/base-url),
 * so preview deploys, self-hosted forks and the canonical Vercel domain all
 * self-describe correctly without env-var overrides.
 *
 * No authentication required — this endpoint is public discovery.
 *
 * Locked by src/oauth-authorization-server.contract.test.ts.
