feat(shell): zsh tooling, tmux plugins, nix-index, nh
zsh: history tuning (100k, dedup, share, timestamps); oh-my-zsh sudo /
colored-man-pages / extract; fzf, zoxide, direnv (+nix-direnv), eza, bat;
ls-family aliases. command-not-found via the prebuilt nix-index DB (+comma).
nh with $NH_FLAKE and a weekly user-GC timer.
tmux: escape-time 10 (was the 500ms default -> laggy vim ESC), focus-events,
base-index 1; plugins sensible / vim-tmux-navigator / yank / catppuccin
(mocha statusline) / resurrect / continuum (restore on); renumber-windows
and set-clipboard.
