fix(classic): fix CI failures - install Playwright and auto-detect model

- Add 'playwright install chromium' step to Forge CI workflow
- Auto-detect default model from available API keys (ANTHROPIC_API_KEY,
  OPENAI_API_KEY, GROQ_API_KEY) in direct_benchmark harness
- Prefer Claude > OpenAI > Groq, fallback to OpenAI if no keys found
