Fix zsh alias error and sync packages across Dockerfiles

Fixed zsh configuration:
- Fixed '?' alias that was causing 'no matches found' error in zsh
- Added proper bat alias (bat → batcat on Ubuntu)
- Added conditional alias handling for different shells

Synchronized packages across Dockerfiles:
- Added bat, mpack, pandoc to Dockerfile.scratch
- Enhanced package cleanup in Dockerfile.scratch
- Both Dockerfiles now have identical package lists

New packages available:
- bat (as batcat) - syntax-highlighted cat alternative
- mpack - MIME email utilities
- pandoc - document converter

All shells (bash, zsh, fish) now work without errors!
