Returns the RFC 8414 authorization-server metadata document for the Charming auth surface. Consumed by MCP clients during the OAuth handshake. The base payload shape is owned by better-auth; Charming splices a WorkOS-style `agent_auth` extension block carrying `register_uri` (`/api/pair/start`), `claim_uri` (`/app/{id}/claim`), `revocation_uri` (`/api/token/{id}`), `skill` (`https://charm.ing/docs/technical-reference/authentication.md`), `identity_types_supported` (`["anonymous"]`), and an `anonymous` sibling block with `credential_types_supported` (`["api_key"]`).
