🔧 Address additional bot feedback issues

Critical fixes:
- Remove duplicate <validation-and-review> opening tag (XML syntax)
- Fix git hook detection bug (check directory not file)
- Add command injection protection for task descriptions
- Improve shell metacharacter validation

These fixes address the second round of bot review feedback,
demonstrating the autonomous feedback handling workflow.
