Anthropic (via LiteLLM/proxy) requires the `tools` parameter to be present when messages include tool_calls or tool role messages, even if no tools are currently being provided. This adds a `hasToolHistory()` helper to detect if the conversation contains tool calls or tool results, and ensures `tools: []` is included in the request params when needed.
