Portal.js bundle without Sentry

[muratcorlu]

Portal.js is a huge library that we download on every single Ghost site. It's ~400KB (compressed, or 1.8MB unzipped).

And 75% of it is Sentry.

I believe only a small fraction of Ghost sites actually enable Sentry, which suggests a significant and unnecessary waste of bandwidth and performance.

To address this, we should consider creating a separate bundle that excludes Sentry, making it the default option.

I’m willing to contribute and prepare a pull request, but before investing considerable effort, I’d appreciate confirmation from the Ghost team that they recognize the need for this optimization.
