feat(auto-mode): skip memory extraction when Claude not configured and add reasoning effort support

- Skip learning extraction when ANTHROPIC_API_KEY is not available
- Add reasoningEffort parameter to simpleQuery for Codex model configuration
- Add stdinData support to spawnProcess for CLI stdin input
- Update UI API types for model override with reasoning support
