fix: add enableCrossOsArchive to cache save/restore for cross-OS artifact transfer

The build jobs save caches on macOS and Windows runners, but the release
job restores them on a Linux runner. actions/cache includes runner.os in
its internal version hash by default, making caches from other OSes
invisible even when the user-specified key matches. Adding
enableCrossOsArchive: true on both cache/save and cache/restore steps
ensures the OS is excluded from the version hash, allowing cross-OS
cache lookup to succeed.
