feat: activate strategic workflows with workspace isolation

WORKFLOW ACTIVATION: Enable critical CI/CD workflows without conflicts

Activated Workflows:
✅ security-scanning.yml - Security vulnerability scanning
✅ cli-level1-tests.yml - CLI command testing (Node.js 18/20)
✅ python-tests.yml - Python testing (already active, now isolated)

Key Improvements:
1. Workspace Isolation:
   - python-tests.yml: /opt/gitea-runner/python-workspace
   - security-scanning.yml: /opt/gitea-runner/security-workspace
   - cli-level1-tests.yml: /opt/gitea-runner/cli-workspace

2. Conflict Resolution:
   - Eliminated workspace wars between workflows
   - Each workflow has isolated workspace directory
   - No more 'rm -rf /opt/gitea-runner/workspace' conflicts

3. Strategic Coverage:
   - Security scanning on every push
   - CLI testing on CLI changes (path-restricted)
   - Python testing on main/develop pushes and PRs
   - Daily CLI tests (6 AM UTC schedule)

4. Trigger Optimization:
   - security-scanning: push, workflow_dispatch
   - cli-level1-tests: push (cli/**), PR, daily, workflow_dispatch
   - python-tests: push (main/develop), PR, workflow_dispatch

Expected Behavior:
- Push to main/develop: All 3 workflows trigger
- Push to cli/**: All 3 workflows trigger (CLI path-specific)
- Pull Request: python-tests + cli-level1-tests trigger
- Manual dispatch: Any workflow can be triggered individually

This provides comprehensive CI/CD coverage with zero conflicts
and optimal resource utilization for the AITBC blockchain platform.
