/**
 * Quick smoke test for ClaudeCodeProvider.
 *
 * Prereqs (pick one):
 *  - Claude Pro/Max subscription: run `claude setup-token`, then set
 *    CLAUDE_CODE_OAUTH_TOKEN=<the token it prints> in your environment
 *    (or pass it as `oauthToken` below).
 *  - Console API key: set ANTHROPIC_API_KEY (or pass `apiKey`).
 *
 * `claude login` alone is NOT sufficient for SDK use — Anthropic gates
 * non-interactive (`claude -p`) invocations behind a separate token.
 *
 * Run:  bun run examples/claude-code.ts
