fix: Skip strip command for cross-compiled binaries in release workflow

- Native strip can't handle ARM64 binaries on x86_64 runners
- Only strip native builds, skip cross-compiled ones
- Cross-compiled binaries are already optimized by Rust
- Fixes 'Unable to recognise the format' error in release builds
