Subject: [PATCH] fix: prevent x64 native module rebuild on ARM64 CI runner

On ubuntu-24.04-arm runners, electron-builder's post-build
@electron/rebuild incorrectly tries to restore native modules
to x64 architecture. The ARM64 g++ compiler doesn't support the
-m64 flag, causing the build to fail.

Setting npm_config_arch=arm64 ensures node-gyp correctly identifies
the host architecture, preventing the erroneous x64 rebuild.
