llm-anthropic 0.25.1

The llm-anthropic tool (a command-line program for using Anthropic's Claude AI models) was updated to version 0.25.1, adding support for a new Claude Opus 4.8 model and a fast mode option for users with that feature enabled. The update also changed how the tool handles max_tokens (the maximum number of words the AI can generate in a single response) by making it default to each model's actual maximum instead of a fixed 8,192 limit.
