Llm4sCohereModule

Registers llm4s-cohere's one provider: the Cohere embedding provider, under the id cohere. Cohere's chat client is a dialect in llm4s-openai-compatible (under the same id: chat and embedding ids are separate namespaces), so this module overrides only embeddingProviders.

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

given ProviderRegistry = ProviderRegistry.ofModules(new Llm4sCohereModule)

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