Update example linked to from README

This example needs to have the latest version with search.

I did this manually, and added a feature:

• Add URL support to code transcripts command #27

So next time I can do it like this:

uv run claude-code-transcripts json https://static.simonwillison.net/static/2025/claude-code-microjs/session_01CKTS4KMKErVGzpfhuRJaA4.json

Had to manually edit it to add the analytics back in:

<script async src="https://plausible.io/js/pa-MRJ708bb-yER7VVw_nywG.js"></script>
<script>
  window.plausible=window.plausible||function(){(plausible.q=plausible.q||[]).push(arguments)},plausible.init=plausible.init||function(i){plausible.o=i||{}};
  plausible.init()
</script>

Ideally I'd like fresh releases of claude-code-transcripts to automatically update that demo somewhere.
