Walkthrough

The changes modify webpack and rspack configuration handling across multiple files. The Vue client and server plugins are updated to explicitly specify which webpack stats to include in the JSON output, ensuring modules, assets, chunks, and entrypoints are available for processing. The base preset introduces a builder-specific parser configuration that sets exportsPresence to 'auto' only when using the rspack builder. The node preset modifies the outputModule experiment to be conditional on the builder type, enabling it only when not using rspack.
