Problem

The admin site serves SQL Explorer's frontend from /static/explorer/*
(e.g. main.5.3.js, styles.css, bootstrap-icons.woff2, logo-main.svg).
In production every one of these 404s.

Root cause

This package is consumed by git rev (django-sql-explorer @ git+…@5.3.0-scrub-hook).
Explorer 5.x has a Vite-built frontend whose compiled output lands in
explorer/static/explorer/ — which is gitignored (it's a build artifact).
A git-rev install runs the Python build backend only; it never runs npm run build.
So the installed package contains just explorer/src/ (un-built source), collectstatic
finds nothing under explorer/, and nginx returns 404 for every asset.

The packaging is already correct — MANIFEST.in (recursive-include explorer *) +
include_package_data=True bundle the built static into the wheel. The only missing
piece is that the frontend must be built before the package is built, which a git-rev
install skips.

Fix

Add release-wheel.yml: on a published GitHub Release, set up Node from .nvmrc,
npm ci → npm run build → python -m build, then attach the wheel (+ sdist) as a
release asset. Consumers install that wheel directly, so the built static ships inside
the package and no Node/Vite toolchain is needed at install or deploy time.

Guards included (this build has a silent-failure mode):

• if APP_VERSION is empty the Vite build emits main..js and still exits 0 — the
  workflow now fails if main.<version>.js is absent.
• the workflow fails if the wheel doesn't contain the built static.

Also removes publish-pypi.yml: it published to the upstream public PyPI project
on every release — wrong for this fork, and it would otherwise fire on the same
release: published event this workflow relies on.

After merge

1. Cut a GitHub Release on tag 5.3.0-scrub-hook → this workflow builds the wheel on the
   pinned Node 20 and attaches it.
2. Repoint voicebot-engine from the git-rev pin to the release-asset wheel URL (separate PR).
