New bin/install.sh downloads self-contained release binaries (ripgrep, fd, bat, fzf, jq) into ~/.local/bin — no sudo, nothing outside $HOME, so they persist across Kasm redeploys with no reinstall. Statically linked where available, so they keep working even after the root fs is wiped. Idempotent: pinned versions already present are skipped. lib/fetch.sh adds arch detection + tarball/raw binary download helpers. zsh/zshrc puts ~/.local/bin on PATH; bootstrap.sh runs the module.
