fix(editor): rebuild script and docs cover both bundles

build-editor.sh was calling npx esbuild directly for editor-entry.js
only, leaving vocab-rank.bundle.js stale when devs used the documented
rebuild path. Switch to npm run build (the single source of truth in
package.json) so both bundles are always rebuilt together. Add
vocab-rank.bundle.js to the sha256 manifest and update the vendor README
to describe both build artifacts.
