feat: Bundle Reporter (#1272)

* feat: Bundle Reporter (Publish)
The `publish` command will output a message of the "total upload"
which includes script + modules showing the original size versus gzip size.

* Added bundle reporter to the initial server start for remote `dev`

* Worker script content is added to the modules processed for bundle reporter.

* handle the .01 KiB variation in tests causing flakes

* Handled this with an addition to the  for stdout which masks the hundredth of a kilobyte variation (± .01 KiB)

* nits by Sunil
