chore: add personal nvim configuration

- Enable relative line numbers for better navigation
- Add zsh shell with interactive mode for aliases/functions
- Add buffer navigation keymaps (Shift+h/l for prev/next)
- Add buffer delete with mini.bufremove
- Configure mini.ai with argument textobject (a)
- Customize mini.statusline with git branch and sign indicators
- Update plugin configurations for debug, gitsigns, and lint

This allows syncing nvim config across multiple machines.
