Merge 0b8a9d1de2 into f84341c574

Add unar as a fallback when unrar is not available for extracting
RAR files. This addresses the issue where unrar has been removed
from Homebrew due to licensing issues.

The extraction now:
- Prefers unrar if available (backward compatible)
- Falls back to unar if unrar is not found
- Shows helpful error message if neither tool is installed
