fix: resolve workflow YAML syntax and implement security safety reset

- Removed conflictive 'workflows: write' permission.
- Added 'Safety Reset for Workflow Files' step to prevent GHA from trying to self-modify configuration files during the PR sync.
- This ensures the PR will only contain technical metadata and V2 documentation, avoiding permission rejections.
