feat: restructure dotfiles with GNU Stow organization

- Reorganize dotfiles into stow/ subdirectories (bash/, git/)
- Add package management system with categorized package lists
- Enhance install.sh with interactive package selection
- Fix package selection logic and improve error handling
- Update dotpull alias to work with new stow structure
- Add comprehensive documentation in README.md

Breaking Changes:
- Dotfiles moved from root to stow/ subdirectories
- Install script now requires user interaction for package selection
- Stow commands now target individual config directories
