#
# Windows MSYS2 packaging step for the triangles daemon + CLI.
# Called from .github/workflows/build-all.yml build-windows-daemon step.
#
# Why a script file instead of inline YAML:
# The GitHub Actions msys2 shell wrapper has shown inconsistent handling of
# multi-line inline run: blocks under `set -e -o pipefail` (silent exits with
# code 1). A committed script file bypasses the YAML → shell translation
# quirks and gives us a known-good artifact that we can also run locally in
# MSYS2 for debugging.
#
# Usage: bash scripts/ci/package-windows-daemon.sh <dist-dir> <bin> [<bin> ...]
# Example: bash scripts/ci/package-windows-daemon.sh daemon-dist trianglesd triangles-cli
