feat(llm): add token usage tracking to Response type master

Add input_tokens and output_tokens fields to enable tracking of token consumption from LLM API calls. Each provider extracts token usage from their API responses: - Anthropic: input_tokens and output_tokens - OpenAI: prompt_tokens and completion_tokens - Ollama: prompt_eval_count and eval_count (None if unavailable) - Mock: supports configurable token counts Also add PartialEq to ResponseContent and ToolCall.
