- prerequisite condition tested fish (was inverted: 'zsh missing and
git/curl/fzf present', so fish was never installed on a working machine)
- run fisher bootstrap inside fish via 'fish -c' (was: 'curl | source' in
bash, which always failed with 'filename argument required')
- download fisher.fish with curl -fsSL to a temp file first (fail on HTTP error)
- resolve configs/ via BASH_SOURCE; when piped (curl | bash) fall back to
the end-4 clone instead of failing on relative paths from an arbitrary CWD
- clone dots-hyprland into mktemp -d, never into the caller's CWD; git -C
style usage so a failed pull can't strand the script's working directory
- set -euo pipefail from the top with a guarded/unguarded audit
- warn visibly that end-4 still runs with --force --skip-backup (kept per decision)
- mkdir -p before config copies; tty-guarded fish warning; ${1:-}
