The available-models endpoint no longer hand-rolls Ollama/OpenAI/Anthropic model listing that was immediately overwritten by provider auto-discovery — auto-discovery is now the single fetch path. This removes a redundant per-refresh network round-trip to each provider, and local-only model listing now goes through the provider classes (which validate the URL for SSRF and send auth headers, so an auth-protected local Ollama now lists its models).
