# Build electerm for loong64 (LoongArch64) Linux
#
# This workflow:
# 1. Builds x64 version with electron v39.2.7 to get the asar
# 2. Downloads electron loong64 v39.2.7
# 3. Cross-compiles native modules for loong64
# 4. Merges x64 asar with loong64 electron and native modules
# 5. Uploads tar.gz to GitHub release draft
# 6. Builds deb package and uploads to GitHub release draft
# 7. Optionally uploads to R2
