Code Review

This pull request updates the dot-env.example file by changing the CLAUDE_MODEL to claude-sonnet-4-6 and commenting out the Google Vertex AI configuration variables. Feedback indicates that claude-sonnet-4-6 is a Vertex AI model identifier and using it for CLAUDE_MODEL (direct Anthropic API) may cause API errors, suggesting to revert it to a valid Anthropic model identifier.

The model identifier claude-sonnet-4-6 appears to be a Google Vertex AI model name (configured as the default for VERTEX_MODEL in lib/config.js). Setting CLAUDE_MODEL (which is used for the direct Anthropic API provider) to claude-sonnet-4-6 will likely result in an API error because the direct Anthropic API expects standard Anthropic model identifiers (or the claude-sonnet-4-5-20250929 default defined in lib/config.js). Consider reverting this to a valid Anthropic model identifier or keeping it consistent with the default in lib/config.js.
