Required tier is now fish, fzf, and zoxide only — the tools the config
meaningfully can't function without. Everything else degrades gracefully.
- cargo: only used by fish-deps to install Rust tools or build fish from
source; all paths are already gated on type -q cargo
- starship: type -q guard in conf.d/starship.fish; shell falls back to
fish's built-in prompt without it
- fisher: auto-bootstrapped by first_run.fish; no need for users or
fish-deps to manage it. Remove from catalog and clean up the now-dead
fisher-bootstrap/special-fisher installer cases.
Catalog arrays verified aligned at 26 entries each.
