# Installs the `nura` command-line client (cross-model memory from the terminal).
# Prefers an isolated tool install (uv → pipx); falls back to pip --user. The
# `nura` CLI also carries the Nuramem skill (`nura skill install`) and the
# multi-client MCP installer (`nura connect`), so this one script bootstraps the
# whole local surface. No sudo; nothing installed system-wide.
