Pull Request Overview
This PR introduces a test application for measuring and comparing the tree-shaking and bundling efficiency of different JavaScript bundlers (tsdown, esbuild, webpack) for the typegpu package as part of CI automation.
- Adds a dedicated treeshake-test application with utilities for bundling and measuring output sizes
- Creates three example TypeScript files to test different import patterns from the typegpu package
- Implements a GitHub Actions workflow to run tree-shaking tests on pull requests
