fix(constants/packages): update remaining .default imports to named exports

Update getters to use named exports from the 5 fixed modules:
- getPackageDefaultNodeRange: use packageDefaultNodeRange
- getPackageDefaultSocketCategories: use packageDefaultSocketCategories
- getPackageExtensions: use packageExtensions
- getLifecycleScriptNames: use lifecycleScriptNames

This completes the transition from default exports to named exports,
fixing runtime errors where modules were returning undefined.
