Make Claude-based tests conditional on API key presence

- Added checks for ANTHROPIC_API_KEY secret availability
- Skip Claude-based API calls when key is not available
- Added helpful warnings in workflow summaries when tests are skipped
- Made artifact uploads conditional on API key availability

This allows the workflows to pass when run in forks or environments
without the API key configured.
