zsh setup

A developer has published a comprehensive Zsh shell configuration that integrates Starship, Fzf, Zoxide, Eza, and Bat into a single setup file. The configuration includes a shared 100,000-entry history across all open shells, case-insensitive tab completions with arrow-key menu selection, and Option/Alt key bindings for word-level cursor movement. The setup also provides aliases for navigation, file listing with Eza, Git commands, and syntax-highlighted file viewing with Bat.
