Fixes from second PR #8 review:
Critical fixes:
- Show how to actually USE $ESCAPED_PATH in final command (not just escape it)
- Add Fish shell function syntax support (uses functions not aliases)
- Add existing alias/function replacement with user confirmation
- Reorder backup timing (after user confirms, before modifying)
Improvements:
- Example output now shows path with spaces to demonstrate escaping
- Added Fish shell syntax explanation section
- Added security considerations section
- Updated "How It Works" for both Bash/Zsh and Fish
- Clear step-by-step command generation with $ESCAPED_PATH
This ensures the shell injection vulnerability is truly fixed by showing
explicit usage of the escaped path variable in the final command generation.
