llm-anthropic 0.23

New plugin release adding support for Claude Opus 4.5, including the new thinking_effort option:
llm install -U llm-anthropic
llm -m claude-opus-4.5 -o thinking_effort low 'muse on pelicans'

This took longer to release than I had hoped because it was blocked on Anthropic shipping 0.75.0 of their Python library with support for thinking effort.
