fix CI: store list pointer on AbstractRange to avoid Page type mismatch

The bridge.finalizer resolves Page through its own module graph, which
can differ from Range.zig's import in release builds. Store a pointer
to the live_ranges list directly on AbstractRange so deinit can remove
without accessing Page fields.
