llm-anthropic 0.30 adds Claude Sonnet 5.5 support

Read original source →simonwillison.net

The release adds Claude Sonnet 5.5 plus an `llm anthropic refresh` command that pulls the Anthropic model list straight from their API, so new models no longer require a plugin release. A new `llm anthropic count` command uses Anthropic's free token counting API to count prompt tokens before sending.
