Improve aliases: safety, consistency, and robustness

[kael-dev-bot]

This PR improves the aliases in zsh/aliases.zsh with enhancements focused on safety, consistency, and robustness:

Phase 1 — Safety & Correctness

1. Guard Nushell aliases with fallback for better compatibility
2. Rename ps to psa to preserve original ps command functionality
3. Add safety to kd with --wait flag for safer kubectl deletes

Phase 2 — Consistency

4. Make Terraform aliases consistent by using tf prefix
5. Consolidate git aliases into one consistent g* scheme:
   • Renamed gc to gco for git checkout
   • Renamed pull to gpl for git pull
   • Added gb for git branch
   • Added glog for enhanced git log viewing

Phase 3 — Robustness & Polish

6. Add error handling to update with success/failure feedback
7. Make gwp robust with error handling
8. Add new Docker aliases for better container management

These changes improve the overall user experience while maintaining backward compatibility where possible.
