Build fixups (#1462)

* (Ironically) ignore build script during package publication:
  - Avoids platform-specific wheels.
  - Ensures build script is not included in sdist.
* Remove legacy Node package build, now that poetry is leading.
* Run builds also for PR's to release branches.

The road to hell is paved with dirty workarounds.
