Pull request overview
This PR extends the build tooling to generate esbuild metafile output on disk and adds a small pr-checks utility script to print bundle sizes, enabling easier tracking of bundle growth over time.
Changes:
- Enable esbuild metafile generation and write the metafile to meta.json during build.mjs.
- Add pr-checks/bundle-metadata.ts and run it at the end of npm run build to print output sizes.
- Refactor pr-checks GitHub API client construction into a shared api-client.ts module.

Modifies the esbuild script to write bundle metadata to disk and adds a small script to print the bundle sizes. The script is run at the end of the build process. We can extend this in the future to provide more detailed insights.
