Playground editor template dropdown is broken — only Hello World works

[Mossaka]

Bug

The template dropdown on the playground editor lists 5 options but only "Hello World" works. Selecting any other template (Issue Triage, CI Doctor, Contribution Guidelines Checker, Daily Repo Status) does nothing — the editor content and URL hash remain unchanged.

Root Cause

Commit c46362c ("remove fetch(url) from editor.js - only allow copy-paste of markdown") removed the 4 non-hello-world template entries from the SAMPLES object in editor.js for security reasons (removing URL fetching), but left the corresponding <option> elements in index.html.

When loadSample(key) is called for any key other than hello-world, SAMPLES[key] returns undefined and the function returns early at the guard clause (if (!sample) return), so nothing happens.

Timeline:

1. cd15cde59b — Added 5 templates with inline content
2. c7913a8fc7 — Changed to URL-based fetching from GitHub
3. c46362c4c7 — Removed URL fetching (security fix), deleted template entries but kept HTML <option> elements ← bug introduced here
4. 2ae13e23dd — Removed CodeMirror; templates still missing

Proposed Fix

Restore the 4 missing template entries as inline content in the SAMPLES object in docs/public/editor/editor.js. The original inline content is available from commit cd15cde59b.

Constraints:

• No new dependencies — the editor is now dependency-free (no CodeMirror) and must stay that way
• No URL fetching — content must be inline in the JS file
• No changes needed to index.html, event handlers, or deep-link logic — they already work correctly, they just need the SAMPLES data populated

Repro

1. Go to https://github.github.com/gh-aw/editor/index.html
2. Select "Issue Triage" (or any template other than Hello World) from the dropdown
3. Observe: dropdown visually changes but editor content stays on Hello World
4. Observe: URL hash stays #hello-world instead of updating

Expected

Selecting any template from the dropdown should replace the editor content with that template's markdown and update the URL hash for deep linking.
