/**
 * Shared Claude Agent SDK call — one place both the Critic and the Designer

 * default, all built-in tools are disabled and denied, `.claude` config is
 * ignored, and there's a wall-clock guard so it can't hang.
 *
 * AUTH: the Claude Code OAuth credential (`claude` login or `CLAUDE_CODE_OAUTH_TOKEN`),
 * billing the maintainer's subscription. `ANTHROPIC_API_KEY` shadows it and
 * reverts to pay-per-token — a one-time warning fires before any billable call.
