[Roadmap] Support for DuckDuckGo search

[joelmnz]

Why
Google API search requires keys and setup, its quite hard to navigate the google api key settings to get this setup + then you are tracked and monitored.

Description
If we could support something like Open-WebUI that uses DuckDuckGo that would be amazing, no login, no keys, just search.

Ref: https://github.com/open-webui/open-webui/blob/main/backend/apps/rag/search/duckduckgo.py

Requirements

• Preferences > Tools > DuckDuckGo search - no settings just a tick box to say use, maybe default to ON by default?
• Use DuckDuckGo in ReAct mode if setting is turned on

Thanks for the idea @joelmnz - we need to have this in the roadmap. In the same spirit we have https://exa.ai/, which could be good to have.

In general we have a few places with multiple providers of a service (in bold what's shipped):

• search: Google, DuckDuckGo, Exa, etc.
• voice: OpenAI, ElevenLabs, Play.ht, Heygen, Wellsaid, Web Speech API
• speech reco: OpenAI, opensource whisper, whisper in AI services, Web Speech API
• image generation: OpenAI, Prodia (cheap stable diffusion), many many more...
• code execution: E2B, Google Code Execution (impl in Big-AGI 2.0), Google Colab API, ...

We'd benefit from a strategy and a framework to allow for configuration, auto-detection, auto-selection of the best, user configuraiton and overrides. Just a dev note.
