Refactor default presets, fix chardet version conflict, improve welcome banner refresh logic

- Rename presets: "Efficiency" → "Max Power", "Intelligence" → "Balance", add "Cost Efficient"
- Update preset models: use Claude Opus 4.6, Sonnet 4.6, Kimi K2.5, GPT-5.4-mini/nano, Gemini 3.1 Flash Lite
- Adjust context lengths and vision capabilities across presets
- Pin chardet<6 to avoid import warnings from requests when unstructured is installed
- Replace settings-updated listener with modal-closed event
