llm-anthropic 0.30: Claude Sonnet 5.5 support and real-time model updates from the API

The llm-anthropic package version 0.30 centers on Anthropic and the Claude Sonnet 5.5 model. The release adds support for Claude Sonnet 5.5 and introduces a new llm anthropic refresh command that can update the available model list directly from the Anthropic API, so the developer does not need to publish a new release for each new model. It also adds an llm anthropic count command that uses Anthropic’s free token-counting API to pre-return the number of tokens a prompt is expected to use. The changes speed up the development cycle, allow real-time adaptation to models, and improve cost and token management for users. The release number is 0.30, and it specifically names Claude Sonnet 5.5 as well as the llm anthropic refresh and llm anthropic count commands. The main impacts are reduced release administration, more accurate upfront token estimates for cost control, and easier integration with new Anthropic models; these changes are primarily important for developers and system administrators but also useful for business actors involved in cost-conscious application development.
