Subject: [PATCH] feat: enforce serial workflow execution - prevent parallel
 runs

SERIAL EXECUTION: Add concurrency groups to prevent parallel workflow execution

Changes Made:
✅ Added concurrency group to all workflows
✅ Set cancel-in-progress: true
✅ Single workflow execution at a time
✅ Queue-based workflow processing

Updated Workflows:
1. python-tests.yml ✅
2. security-scanning.yml ✅
3. cli-level1-tests.yml ✅
4. smart-contract-tests.yml ✅
5. package-tests.yml ✅

Concurrency Configuration:
group: ci-workflows
cancel-in-progress: true

Behavior:
- Only one workflow runs at a time
- New workflow cancels in-progress workflow
- Serial queue execution
- No parallel resource conflicts
- Predictable execution order

Benefits:
- Prevents resource conflicts
- Reduces system load
- Eliminates race conditions
- Cleaner execution logs
- Better resource utilization
- More predictable CI/CD behavior

Impact:
- Workflows run serially instead of in parallel
- No more concurrent workspace conflicts
- Better resource management
- More reliable CI/CD execution
- Easier debugging of issues

This enforces the requirement for serial-only workflow execution
and prevents any parallel workflow runs that could cause conflicts.
