name: Build release artifacts

# Builds each platform natively on a v* tag and publishes one Gitea release.
#
# Runners required. None are registered yet, and a job with no matching runner
# queues silently rather than failing, so register all three before tagging:
#   ubuntu-latest   Linux AppImage
#   windows-latest  Windows NSIS installer + portable zip
#   macos-arm64     macOS dmg + zip, both architectures (M-series builds both)
#
# Nothing cross-builds any more: dmg requires macOS, and the Windows exe needs
# rcedit on Windows to get its icon and version resources.
#
# All output is unsigned. Once certificates exist: for macOS drop mac.identity
# from package.json and remove CSC_IDENTITY_AUTO_DISCOVERY; for Windows add the
# cert secrets. Until then users hit Gatekeeper and SmartScreen warnings.
