Problem: rsync with trailing slashes copied directory contents to wrong location
Solution: Created automated deployment script with correct patterns
Changes:
- Created scripts/deploy-security-middleware.sh (automated deployment)
- Created docs/DEPLOYMENT_RSYNC_PATTERNS.md (rsync best practices)
- Cleaned up incorrectly placed files on production
- Documented trailing slash behavior and correct patterns
This prevents future deployment issues and provides reliable automation.
