v5-redux: Clean dotfiles rewrite — zsh, git, tmux, ghostty, install.sh

[davidstosik]

What is this?

A complete rewrite of the dotfiles, continuing v4's philosophy of radical simplification while bringing back the best from older branches (v1-v3, wip-20241205).

Note: This PR targets v4 because the branch histories diverge. Neovim config lives in a separate PR (#3), and package management via mitamae in PR #4 — both targeting this branch.

What was brought back from older branches

From v1-v3:

• Git aliases: lola (log all), lolg (log graph), addu, br, cp, up, copr (checkout PR)
• Shell aliases: ls with colors (macOS/Linux), safety aliases (rm -i, cp -i, mv -i), navigation (.., ...)
• Shell functions: mkcd (mkdir + cd, from v3)
• tmux: renumber-windows (v1), synchronize-panes toggle (v3)

From wip-20241205:

• Ruby aliases (be, r, rb)
• Git aliases (cob, cim, cia, ciam, recent)

From v4 (all preserved):

• Tokyo Night theme (tmux, ghostty)
• vpn-fix function
• Modern git config (histogram diff, zdiff3 merge, rerere, autoSquash, etc.)
• Ghostty config (Monaspace font, transparency, ligatures)
• tmux-resurrect, tmux-sessionx
• mise integration

What was intentionally left out

What	Why
LazyVim framework	Too much hidden magic, hard to debug (neovim in separate PR #3)
Antigen / oh-my-zsh (v3)	Heavy, slow startup, most plugins unused
rbenv (v1-v3)	Replaced by mise
nvm (v4)	Replaced by mise
The Silver Searcher (v3)	Replaced by ripgrep
tmux-sensible	Settings ported directly into tmux.conf
tmux-pain-control	Replaced by explicit keybindings
tmux-continuum (v1)	resurrect alone is enough
Hub (v1-v2)	Replaced by gh CLI
base16 colors (v1)	Replaced by Tokyo Night
Modular install system (v3, wip)	Simpler approach with install.sh
Dockerfile (wip)	Unnecessary for personal dotfiles
iCloud sync scripts (wip)	Too machine-specific
Scripty (wip)	Niche, doesn't belong in dotfiles

Install

git clone https://github.com/davidstosik/dotfiles ~/.dotfiles
cd ~/.dotfiles

# Link dotfiles
./install.sh

Then:

1. Restart shell (or source ~/.zshrc)
2. In tmux: C-a I to install plugins

Tip: For package installation, see PR #4 (mitamae).

Commits

Each commit is atomic and self-contained:

1. feat: zsh — structured config with aliases and functions
2. feat: git — consolidate config from all branches
3. feat: tmux — reorganize and cherry-pick improvements
4. feat: ghostty — move to XDG-standard config location
5. feat: add install.sh and README
