test(commonjs): add regression for wrapped external Node built-ins under strictRequires

- New fixture: module-side-effects-external-node-builtin-wrapped
- Ensures transform doesn’t crash when resolving moduleSideEffects for wrapped externals
- Provides __filename in test context to avoid env-dependent failures
