fix: normalize dot-versioned model names for Anthropic API

Browse source 
anthropic/claude-opus-4.6 (OpenRouter format) was being sent as
claude-opus-4.6 to the Anthropic API, which expects claude-opus-4-6
(hyphens, not dots).

normalize_model_name() now converts dots to hyphens after stripping
the provider prefix, matching Anthropic's naming convention.

Fixes 404: 'model: claude-opus-4.6 was not found'
