build-stdiod.sh

#!/usr/bin/env bash
# Build the edison-stdiod daemon as a universal macOS binary and stage it
# into client_2/bin/ so electron-builder's mac.extraResources rule can copy
# it into Contents/Resources/bin/ of the packaged .app.
#
# Why universal: electron-builder.yml sets mac.target: universal, which
# requires every nested binary inside the .app to also be a universal
# Mach-O - otherwise the universal merge step fails. We build both arches
# with cargo and stitch them with lipo.
#
# Why outside resources/: keeping the staged binary in a top-level bin/
# directory means it does NOT match the default `files` glob (which
# captures resources/**) and so isn't double-included in the asar.
# electron-builder picks it up only via the explicit extraResources rule.
