WebSearchTool breaks the DevUI

[geoand]

Chatting with the model in 0.15.0 is no longer possible, but instead we get:

{"id":12,"error":{"code":-32603,"message":"Method [io.quarkiverse.langchain4j.quarkus-langchain4j-core.chat] failed: No bean found for required type [class dev.langchain4j.web.search.WebSearchTool] and qualifiers [[]]"},"jsonrpc":"2.0"}

The reason this happens is because LangChain4j now includes dev.langchain4j.web.search.WebSearchTool#searchWeb which is annotated with @Tool, but we don't create a bean for this class.

As a first step, we should not consider this class a tool unless there is an implementation of WebSearchEngine (this isn't fool proof, but it's good enough for now)

I will fix this, but @jmartisk I think we need some sort of smoke test for the chat interface of the DevUI

@phillip-kruger are there any existing Dev UI tests that actually work with the UI?

[phillip-kruger]

There are tests for jsonrpc calls and tests for build time data. There are no Ui tests (as in playwright)
