#!/bin/sh
# STET CLI installer (POSIX) — detects the platform, downloads the right static
# binary, and puts it on PATH. Served with the base URL stamped in:
#   curl -fsSL <base>/cli/install.sh | sh
#
# (This replaced a dev helper that symlinked the repo's working copy onto PATH.
# Never do that: every agent on the machine then runs uncommitted code, and an
# unstamped copy silently disables `stet version` and the outdated-CLI nudge.
# Dev testing invokes the build directly — go build -o /tmp/stet ./cli && /tmp/stet.)
