Rule violated: Event provisioning surfaces

Offending change: This PR removes the <!-- reuse:event-org-readme-intro:start --> and <!-- reuse:event-org-readme-intro:end --> HTML reuse markers that wrapped the intro paragraph.

Guideline (Event provisioning surfaces):

When you change workshop onboarding language that should also appear in those provisioned surfaces, update the marked source blocks in workshop/00-welcome.md and keep the examples in sync.

The reuse markers exist so downstream event-provisioning tooling can extract and copy the intro text into org-profile READMEs and learner-repo Codespace launchers. Removing them breaks that sync contract.

Suggested fix: Restore the reuse markers around the intro paragraph:

<!-- reuse:event-org-readme-intro:start -->
By the end of this workshop, a real AI agent will create an issue with a summary of the activity in your repository over the latest 24h, every day, without you writing shell-script workflow code.
<!-- reuse:event-org-readme-intro:end -->

If the event-provisioning examples are intentionally being retired, also update the Event provisioning surfaces section of .github/workflows/guidelines.md in this PR to reflect that change.
