Concept Model Provider

<!-- Canonical one-paragraph definition. Edit here; reuse via {{#include}}. -->

Model provider. A model provider is ZeroClaw's abstraction over an LLM endpoint. Every chat-completion request goes through a provider, whether the target is a remote API, a self-hosted server, or a local Ollama model. Providers are typed by vendor family, and you can run several named instances of the same family. In the config each one lives at [providers.models.<type>.<alias>]. See Model Providers → Overview.
