fix: use zsh idioms and quote variables in shell config

- Use [[ ]] instead of [ ] for conditionals (zsh idiom)
- Quote variable expansions in ZINIT_HOME checks and dirname call
- Quote dollar-1 in mkcd function
- Remove extra blank line in .vimrc

-# dotfiles
-
-Personal dotfiles managed as a bare Git repository. The repo lives at `~/.dotgit/` with the work tree set to `$HOME`, so tracked files sit at their real paths without symlinks.
-
-## Bootstrap
-
-```bash
-# Clone bare repo
-git clone --bare https://gitea.abra.me/svxf/dotfiles.git "$HOME/.dotgit"
-
-# Checkout files into $HOME
-git --git-dir="$HOME/.dotgit/" --work-tree="$HOME" checkout
-
-# Hide untracked files from status noise
-git --git-dir="$HOME/.dotgit/" --work-tree="$HOME" config status.showUntrackedFiles no
-```
-
-After checkout, restart your shell. Zinit and Starship will self-install on first launch.
-
-## Usage
-
-The `.g` alias wraps `git --git-dir=$HOME/.dotgit/ --work-tree=$HOME`, so everyday operations look like:
-
-```bash
-.g status
-.g add ~/.vimrc
-.g commit -m "update vimrc"
-.g push
-```
-
-A background job in `.zshrc` auto-pulls once per day (`~/.cache/.dotfiles-pull` marker).

-- **Plugin manager**: Zinit (auto-installed from `zdharma-continuum/zinit`). Plugins: `zsh-autosuggestions`, `zsh-syntax-highlighting`, `zsh-completions`, `zsh-history-substring-search`.
-- **History**: 100k entries, shared across sessions, deduped, extended format.
-- **Completions**: Case-insensitive matching, menu selection.
-- **Keybindings**: Emacs mode. Ctrl+Q push-line, Alt+E / Ctrl+X,E edit-command-line, Up/Down prefix search.
-- **Prompt**: Starship (installed via Zinit from GitHub releases).
-- **fzf integration**: Keybindings and completion sourced when available; `--height 40% --reverse` default opts.
-- **PATH**: `/projects/bin`, `~/.local/bin`, `~/.cargo/bin`, `/usr/local/go/bin`, `~/go/bin`, `/opt/homebrew/bin`.
-- **Aliases**:
-  - `.g` — bare-repo git wrapper
-  - `tmuxr` / `tmuxn` / `tmuxa` — tmux attach-or-create helpers
-  - `,dcdu` / `,dcdd` / `,dcdl` — docker-compose dev-profile shortcuts
-  - `dcu` / `dcd` / `dcl` — generic docker-compose shortcuts
-  - `c` / `,cd` — Claude CLI / Claude with sandbox skip
-  - `LATEST` — global alias expanding to most-recently-modified file
-- **Functions**:
-  - `y` — yazi file manager wrapper that `cd`s to the selected directory on exit
-  - `pj` — fuzzy project switcher (searches `/projects` and `~/projects` via fzf)
-  - `clip` — pipe stdin to system clipboard via OSC 52 escape sequence
-  - `mkcd` — mkdir + cd in one step
-  - `cdtmp` — create and cd into a timestamped temp directory under `~/tmp/`
-- **Extras**: `~/.zshrc-extra` sourced at end for machine-local overrides (not tracked).
-
-### .tmux.conf
-
-- **Mouse** enabled, clipboard passthrough on.
-- **Splits** preserve current path.
-- **Navigation**: Shift+Arrow switches windows (no wrap), Alt+Arrow switches panes, PgUp/PgDn swaps window order.
-- **Window naming**: Auto-rename to `command@dir`.
-- **Fuzzy switcher**: `prefix + f` opens fzf popup to pick a window.
-- **Status bar**: Dark theme (colour235 bg), green session indicator, powerline-style window tabs with alternating shading, no right-side status.
-- **Pane borders**: Green active, grey inactive.
-- **Base index**: 1 (not 0).
-
-### .vimrc
-
-- `jk` mapped to Escape, Space as leader.
-- 4-space soft tabs, syntax on, cursor line highlighted.
-- Persistent undo (`~/.vim/undo/`), swap and backup dirs under `~/.vim/`.
-- Smart case search, incremental + highlighted.
-- Arrow keys disabled in normal mode (forces hjkl).
-- Mouse support enabled, 8-line scroll margin.
-
-### .starship.toml
-
-Two-line prompt:
-
-- **Line 1** (left → right): Docker container indicator (if inside), docker-compose service summary (running/stopped counts), git branch + status, fill, directory.
-- **Line 2**: `➤` character (green on success, red on error).
-- **Right prompt**: Command duration (>5s), `user@host`, time.
-- Docker-compose status uses `docker compose ps --format json | jq` to show `▲N/▼N` counts.
