 * OAuth Authorization Endpoint

 * loginPath hook) and a Harper credential fallback. If the user has an
 * active session (from a prior OAuth login), issues an auth code
 * immediately.
 *
 * Authorization decisions (who gets access, what scopes) are delegated
 * to the host application via the onAccessCheck hook on each MCP request.
