Fix docs deployment asset path and enable live bidirectional conversion in demo

[Copilot]

Docs are now deployed from docs/, but the demo page still loaded JSURL from ../dist/index.js, which is absent in Pages artifacts. This updates deployment to publish the runtime into docs/ and makes JSON↔JSURL conversion run continuously while typing.

• Docs deployment artifact

  • Update Pages workflow to build the library before upload.
  • Copy dist/index.js to docs/index.js so the demo has its runtime in deployed artifacts.

• Demo page runtime + live editing

  • Change demo script source from ../dist/index.js to ./index.js.
  • Add oninput handlers on both textareas to perform immediate conversion in both directions.
  • Keep existing button-based conversion/beautify flows intact.

• README cleanup

  • Remove stale Live editor: https://cv122s.csb.app/ entry.

• Focused regression coverage

  • Add a docs-focused test that asserts:
    • the demo references ./index.js
    • both live oninput conversion hooks are present

<script src="./index.js" type="application/javascript"></script>

<textarea
  id="json"
  oninput="javascript:execute('json', 'jsurl', json2jsurl)"
></textarea>

<textarea
  id="jsurl"
  oninput="javascript:execute('jsurl', 'json', jsurl2json)"
></textarea>

Pull request overview

This PR updates the GitHub Pages docs deployment so the demo page can load the JSURL runtime from within the deployed docs/ artifact, and enhances the demo UX by running JSON↔JSURL conversion live while typing.

Changes:

• Update the Pages workflow to build the library and publish the browser runtime into docs/.
• Switch the demo page to load ./index.js and add oninput handlers for continuous bidirectional conversion.
• Remove the stale “Live editor” link from the README and add a regression test covering the docs demo wiring.
