feat(ci): implement comprehensive GitHub automation workflows

Implemented full GitHub automation system from claude-code-skills-factory
with project-specific configuration for claude-skills repository.

## New Workflows

- **ci-quality-gate.yml**: Automated linting, testing, and security checks
- **claude-code-review.yml**: Enhanced with kill switch and bypass mechanisms
- **pr-issue-auto-close.yml**: Auto-close linked issues when PRs merge
- **smart-sync.yml**: Bidirectional sync between issues and project board

## Configuration Files

- **WORKFLOW_KILLSWITCH**: Emergency workflow disable capability
- **branch-protection-config.json**: Branch protection settings
- **commit-template.txt**: Standardized commit message template
- **AUTOMATION_SETUP.md**: Complete setup and configuration guide

## Templates

- **pull_request_template.md**: Enhanced with security and quality checklists

## Key Features

✅ AI-powered code reviews with Claude
✅ Automatic issue closure on PR merge
✅ Bidirectional issue ↔ project board sync
✅ Quality gates (YAML lint, Python syntax, security audit)
✅ Kill switch for emergency workflow disable
✅ Rate limit protection with circuit breakers
✅ 10-second debouncing to prevent sync loops

## Project Configuration

- Repository: alirezarezvani/claude-skills
- Project Number: 9
- Status: Ready for PROJECTS_TOKEN configuration

## Testing

Workflows validated with yamllint and ready for deployment.

See .github/AUTOMATION_SETUP.md for complete setup instructions.
