fix: correct shell config bugs in .zshrc and .zsh_aliases

[tschulze]

Summary

• Remove trailing visudo from EDITOR and VISUAL exports in .zshrc and .zsh_aliases — the value was being set to "nvim visudo" instead of "nvim", breaking any tool that invokes $EDITOR
• Guard the fzf preview alias with a bat availability check and fall back to cat when bat is not installed
• Fix missing # on the Zoxide and Tmuxifier comment lines in .zshrc (bare text was being executed as commands)
• Comment out the zoxide and tmuxifier eval lines
• Rename zsh-syntax-highlightin-tokyonight.zsh → zsh-syntax-highlighting-tokyonight.zsh (missing g)
• Remove a duplicate _SKIP_* variable block that was accidentally pasted inside the nnn plugin if-block in .zsh_aliases, causing all those variables to be reset whenever nnn is installed

Test plan

• Source .zshrc and verify echo $EDITOR returns nvim
• Verify fzf preview works with and without bat installed
• Confirm no shell errors on startup related to the Zoxide/Tmuxifier lines

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

Shell configuration files are corrected to remove accidental visudo text from EDITOR/VISUAL exports, fix a typo in the zsh-syntax-highlighting script filename, make the fzf preview command conditional on bat availability, and disable zoxide and tmuxifier initialization.

Changes

Shell Configuration Cleanup

Layer / File(s)	Summary
Environment Variable Fixes .config/alias/.zsh_aliases, .zshrc	EDITOR and VISUAL exports corrected to remove the unintended visudo suffix; both now export only vim and nvim respectively.
Conditional Tool Integration .zshrc	fzf alias preview command now conditionally uses bat when installed, falling back to cat otherwise.
Script Sourcing & Initialization .zshrc	Typo in zsh-syntax-highlighting tokyo-night script filename is fixed; zoxide and tmuxifier eval init blocks are commented out while preserving configuration comments.

🐰 A rabbit hops through configs bright,
Removing visudo—cleaning up the sight,
With bat as a friend and typos all gone,
The shell flows more smoothly from dusk until dawn! ✨
