From 44 requests to one: esbuild bundling

Until now the module loaded around 44 separate JavaScript files in the frontend. As of v4.30.0 everything is combined into a single bundle with esbuild.

What that gets you:

• One request instead of ~44 — faster loads, fewer roundtrips.
• CSP-friendly — fits strict content security policies.
• Real stack traces — thanks to a source map (only with DevTools open) you land in the actual source.

No build tool needed on your side: the finished bundle ships in the release.
