# Linux packaging step for the triangles daemon + CLI .deb.
# Called from .github/workflows/build-all.yml build-linux-daemon step.
#
# Builds a self-contained .deb with trianglesd, triangles-cli, bundled libs,
# Tor, systemd service, and CLI launchers. Designed to be reproducible and
# debuggable outside the CI environment.
#
# Usage: bash scripts/ci/package-linux-daemon.sh <version>
