Update all Claude Code GitHub Action workflows to use the latest Sonnet 4.5 model (claude-sonnet-4-5-20250929) instead of the default Sonnet 4.0 model. This provides improved performance and capabilities for:
- Issue commenting and PR reviews (claude.yml)
- Automated issue triage (claude-issue-triage.yml)
- Duplicate issue detection (claude-dedupe-issues.yml)
