EmbeddingProvider

Text embedding provider interface for generating vector representations.

Provides a unified interface for different embedding services (OpenAI, VoyageAI, Ollama). Each implementation handles provider-specific API calls and response formats.

Text content is the primary input; multimedia content (images, audio) should be processed through the UniversalEncoder façade which handles content extraction before embedding.

== Usage Example ==

val provider: EmbeddingProvider = OpenAIEmbeddingProvider.fromConfig(config)
val request = EmbeddingRequest(
 input = Seq("Hello world", "How are you?"),
 model = EmbeddingModelName("text-embedding-3-small")
)
val result: Result[EmbeddingResponse] = provider.embed(request)
