Code Review

This pull request bumps the version to v0.42.0-preview.1, updates the preview changelog with a cherry-pick entry, and refreshes third-party license notices in the VS Code companion package. The majority of the code changes are stylistic formatting updates across the monorepo, primarily affecting the layout of dynamic imports and interface definitions. I have no feedback to provide.
