Add RedLight/GreenLight/YellowLight workflow template orchestration

[Copilot]

Implements organization-wide GitHub Actions workflow templates using a traffic light orchestration pattern for standardized CI/CD across all BlackRoad-Cloud repositories.

Templates Added

• 🔴 RedLight - Quality gate enforcement blocking PRs on test/security/lint failures
• 🟡 YellowLight - Manual approval workflow with environment gates for staging/production
• 🟢 GreenLight - Full automated deployment pipeline with health checks and auto-rollback

Structure

├── redlight.yml              # Validation + blocking logic
├── yellowlight.yml           # Approval gates + deployment controls
├── greenlight.yml            # Test → Build → Deploy → Verify
├── *.properties.json         # GitHub Actions UI metadata
└── README.md                 # Orchestration patterns + usage

Usage

Templates appear in Actions → New workflow for all org repositories. The $default-branch placeholder auto-resolves to each repo's default branch (main/master/etc).

Orchestration patterns supported:

• Sequential: RedLight → YellowLight → GreenLight
• Parallel: Multiple RedLight checks → GreenLight
• Hybrid: RedLight → GreenLight (staging) → YellowLight → GreenLight (prod)

Each template includes placeholder comments for project-specific commands (test runners, deployment scripts, notifications).
