- Cache initial config using useRef to prevent repeated loadConfig() calls
- Fix useEffect dependencies to only trigger on actual config changes
- Modify debouncedSaveConfig dependency from function reference to actual config values
- Update handleConfigReset to use DEFAULT_CONFIG directly instead of reloading
- Prevent excessive console logging during chat interactions and frequent re-renders
This resolves the issue where console was flooded with:
"配置已从本地存储加载" and "配置已保存到本地存储" messages,
especially during active chat sessions where logs appeared every second.
Fixes: Frequent config load/save operations causing performance issues
