Zig's Mach-O linker does not emit LC_ENCRYPTION_INFO_64 for physical
iOS dylibs. This allows libghostty-vt to build successfully but causes
frameworks containing it to fail App Store validation.
I think it'd be cleaner to always just build Apple targets on Apple hosts
with the native linker. We don't need to rely on Zig being correct and
this helps ensure compatibility for details like this.
Add `set -euxo pipefail` to `check-translations.sh` to ensure the CI
fails when contributors do not update the POT file with their changes.
Currently, the CI passes even if the POT file is outdated and the POT
has not been updated for a long time.
