WRNexusJS 0.4.0 UI reference determinism fix

This fixes the release loop where generate-ui-component-reference.mjs writes one layout and Prettier rewrites it differently. The generator now formats both generated files with the repository Prettier configuration before writing them.

Replace:

• scripts/generate-ui-component-reference.mjs

Then run:

bun run scripts/generate-ui-component-reference.mjs
bun run format
bun run format:check
git add scripts/generate-ui-component-reference.mjs packages/ui/component-reference.json packages/ui/COMPONENTS.md
git commit -m "fix(release): make UI reference generation deterministic"
git push origin main
bun run release:private
