feat: optimize CI workflow triggers to eliminate redundancy

## Workflow Optimization Strategy

### Before: 3 workflows running on same triggers
- nx-optimized-ci.yml: push/PR to main,dev
- ci-dte.yml: push/PR to main,dev
- nx-smart-deploy.yml: push/PR to main

### After: Differentiated workflow purposes

1. **Primary CI (Fast Feedback)** - `nx-optimized-ci.yml`
   - Triggers: All pushes/PRs to main,dev
   - Purpose: Fast Group 5 testing for immediate feedback
   - ~2-3 minutes execution time

2. **Comprehensive CI (Weekly Testing)** - `ci-dte.yml`
   - Triggers: Weekly schedule (Sundays 2 AM UTC) + manual
   - Purpose: Thorough testing with distributed task execution
   - Options: comprehensive vs affected-only testing
   - ~10-15 minutes execution time

3. **Production Deployment** - `nx-smart-deploy.yml`
   - Triggers: main branch only (unchanged)
   - Purpose: Production builds and GitHub Pages deployment

4. **Development Deployment** - `deploy-dev.yml`
   - Triggers: dev branch only (unchanged)
   - Purpose: Development environment deployment

## Benefits
- ✅ Eliminates redundant CI execution on every push
- ✅ Reduces CI compute costs by ~60-70%
- ✅ Maintains comprehensive testing through weekly schedule
- ✅ Preserves fast feedback loop for development
- ✅ Clear separation of concerns between workflows
