stage-runtime-lib.sh

#!/usr/bin/env bash
# Ensure libecho_runtime.a (or .lib) is available next to a cargo profile dir so
# `xo run` / AOT link can find it without scanning hashed deps names.
#
# Usage:
#   scripts/ci/stage-runtime-lib.sh [debug|release]
#
# Finds the newest libecho_runtime*.a / echo_runtime*.lib under
# target/<profile>/ and target/<profile>/deps/, copies to
# target/<profile>/libecho_runtime.a (or echo_runtime.lib).
