fix: use native runners for macOS builds to enable CGO

Previously, the workflow attempted cross-compilation for x86_64 builds
on arm64 runners, which forced CGO_ENABLED=0. This broke SQLite support
because mattn/go-sqlite3 requires CGO.

Changes:
- Use macos-13 (Intel) for x86_64 builds
- Use macos-latest (Apple Silicon) for arm64 builds
- Remove cross-compilation logic that hardcoded CGO_ENABLED=0
- Now CGO_ENABLED=1 from scripts/package-macos.sh is properly used

This fixes the "go-sqlite3 requires cgo to work" error.
