CRITICAL: Previous commit 0984684 did not include these fixes.
Debian (debian/rules):
- Use && to keep cargo build in same shell as . "$HOME/.cargo/env"
- Make runs each recipe line in a separate shell
Arch (build-arch.sh):
- Use << "EOF" heredoc with hardcoded path to prevent $pkgdir expansion
- $pkgdir must be literal for makepkg to expand at runtime
Alpine (build-alpine.sh):
- Copy signing public key to /etc/apk/keys/ BEFORE abuild
- Use || true on abuild because index update may fail but APK is still created
debian/rules: Escape $HOME for make (use $$HOME)
- Make interprets $H as variable, $$ escapes it
build-alpine.sh: Install signing public key
- Copy .abuild/*.rsa.pub to /etc/apk/keys/
- Fixes UNTRUSTED signature error on index update
build-arch.sh: Use /home/builduser/repo for all paths
- PKGDIR=/home/builduser/repo/arch-package
- WORKSPACE_DIR=/home/builduser/repo
- Fixes permission denied on act cache path
debian/rules: Source cargo env before calling cargo
- Add `. "$HOME/.cargo/env"` to override_dh_auto_build
build-alpine.sh: Use /home/builduser for all paths
- PKGDIR=/home/builduser/apk-package (accessible by builduser)
- WORKSPACE_DIR=/home/builduser (for APKBUILD package function)
- Removed duplicate else line
build-arch.sh: Copy repo to accessible directory
- Copy repo contents to /home/builduser/repo before makepkg
- Run makepkg in /home/builduser/repo (not act cache path)
