Pull request overview
This PR optimizes bailout reason data by filtering out "ModuleConcatenation bailout" messages from the bailout reasons collected for modules. These messages are deemed less useful for analysis and are now excluded when processing module graph data from both webpack stats and Rspack native plugins.
Changes:
- Added filtering logic to exclude ModuleConcatenation bailout messages when processing optimizationBailout data
- Modified bailoutReason serialization to always include the field regardless of brief mode
- Added comprehensive test coverage for the new filtering behavior in Rspack transform
