[Enhancement]: Add Exa.ai as Web Search Provider

[GPTLeonard]

What features would you like to see added?

I would like LibreChat to support Exa.ai as a native web search provider. Currently, LibreChat requires multiple APIs (Serper/SearXNG for search, Firecrawl for scraping, Jina/Cohere for reranking) to enable web search. Exa.ai offers all of these capabilities in one unified API: semantic search, crawling, content extraction, summaries, and answers.

More details

• Exa.ai already integrates seamlessly with other platforms like OpenRouter and OpenWebUI, where it is used as a real-time web search backend.
• Exa.ai provides a simple pay-per-use model that could significantly reduce cost and complexity for LibreChat users compared to maintaining 3 different APIs.
• Adding Exa.ai would give users the option to configure a single provider instead of juggling multiple services and keys.
• This would also align LibreChat with OpenAI’s GPT-OSS documentation, where Exa.ai is listed as a supported web search option.
