Llm4sWatsonXModule

Registers llm4s-watsonx's provider: the IBM watsonx.ai text-generation client, under the id watsonx.

'''Beta - built on deprecated endpoints.''' IBM's February 2026 release notes (https://www.ibm.com/docs/en/software-hub/5.3.x?topic=new-watsonxai) deprecate the watsonx.ai "Infer text" and "Infer text event stream" endpoints (/ml/v1/text/generation and /generation_stream) this module uses; IBM points to the chat API. This module has never been run against the live service (no watsonx account), its API is not frozen, and tools are unsupported because of the endpoint. Migration to the chat API: https://github.com/llm4s/llm4s/issues/1314.

Declared in this module's META-INF/services/org.llm4s.llmconnect.spi.Llm4sProviderModule, so adding the llm4s-watsonx dependency is all it takes for ProviderRegistry.default to resolve provider = "watsonx". Where discovery cannot run - a fat jar whose services files were overwritten rather than merged - register it explicitly:

given ProviderRegistry = ProviderRegistry.ofModules(new Llm4sWatsonXModule)

A class rather than an object because java.util.ServiceLoader instantiates the class named in the services file through its public no-arg constructor.
