feat: add CI/CD-friendly issue management system

- Add YAML issue forms for structured bug/feature/feedback submission
- Add automated triage workflow with keyword-based auto-labeling
- Add stale issue management (60d issues, 45d PRs, auto-close)
- Add PR link validation and file-based auto-labeling
- Add label definitions (type, priority, status, component)
- Add comprehensive documentation in .github/README.md
- Update CLAUDE.md with issue management section
- Update repository structure diagram

Implements minimal, maintainable issue tracking with:
- 3 issue templates (bug, feature, feedback)
