Kali-style shell on top of omz; p10k fallback via KALI_PROMPT (#612)

Port of Kali's stock kali-zsh-config as ~/.config/zsh/kali-comforts.sh:
twoline prompt, menu-select + case-insensitive completion, keybindings,
color aliases, syntax-highlight palette. Loaded last; omz untouched.

# ~/.config/zsh/kali-comforts.sh — chezmoi-managed
# Kali Linux default zsh experience (kali-zsh-config) layered on
# oh-my-zsh: options, keybindings, completions, the twoline prompt,
# color aliases and the Kali syntax-highlight palette.
# Prompt toggle: KALI_PROMPT=0 in ~/.zshrc restores powerlevel10k.
