fix(vm): increase RAM to 8GB and fix Hyprland rule syntax to prevent crashes

- Increase VM memory to 8192MB to avoid OOM kills during session startup.
- Migrate all 'windowrule' to 'windowrulev2' in core configuration.
- Fix 'no_anim' syntax in layer rules.
- Re-enable graphics while keeping serial logs for debugging.
