Configuration requires unused options

[rachwalk]

This function used for loading:

rai/src/rai_core/rai/initialization/model_initialization.py

Line 99 in 59d0e89

def load_config(config_path: Optional[str] = None) -> RAIConfig:

requires that all vendors have defined options, which is fine when using a default configuration, but a bit bothersome when creating a custom deployment.

To illustrate:

[vendor]
simple_model = "ollama"
complex_model = "ollama"
embeddings_model = "ollama"

[ollama]
simple_model = "qwen3.5:9b"
complex_model = "qwen3.5:9b"
embeddings_model = "qwen3.5:9b"
base_url = "http://localhost:11434"

This config fails to load, even though I am certain that I will not be using any other vendor. I think it would be beneficial to support such minimal configs for users.
