feat: support tree shaking

[gclark-eightfold]

SUMMARY:

Adds tree-shaking support for apps using Octuple. Core changes:

1. Add explicit sideEffects to package.json for CJS tree shaking.
2. Switch from Webpack to Rollup to support exporting ESM.

For the Webpack -> Rollup change, it may be possible to export ESM from webpack, but most sources I found said exporting ESM from webpack was not supported. Additionally, after examining quite a number of specifically react component libraries, it seemed like Rollup was the most common tool for this job.

Testing on Eightfold for the careerHub entry point only yielded a -20.9% decrease in the bundle size for the octuple chunk compared to v2.51.1

Here is the bundle analysis diff in Blindfold.ai after following the steps outlined in the Test Plan

This test plan relies on running Blindfold locally, but can be done in isolation if desired

1. Clone the https://github.com/EightfoldAI/blindfold repo locally
2. In the root of the repo, add the following .env file. (If you have one already, just add ANALYZE_BUNDLES=1

4. Install deps with pnpm install. (Run npm install -g pnpm if you do not have pnpm installed)
5. Run pnpm build --filter nextjs to build the Blindfold app.
6. Once complete open the file located in apps/nextjs/.next/analyze/client.html in your web browser.
   • [x] The bundle analysis does not show the entire octuple.js bundle present.
7. Run pnpm start --filter nextjs and go to http://localhost:8000/octuple
   • [x] Verify the Octuple primary button is present on the page and styled correctly.
8. Remove the patch with pnpm patch-remove @eightfold.ai/octuple
