[Feat]: Publish to NPM

[anuraghazra]

• Setup proper release pipeline with changesets
• Use a better bundler eg vite or rollup so we can target dual cjs/esm bundles
• Publish to NPM
• Keep CDN packaged publishing too

It might be good to drop the .js. Make the github repo and the npm package just be Verly. It's shorter, and assumed that if it's on npm, it's going to be js implicitly. :)
