[Copilot]

Removes the Copy button and all associated code from the playground editor UI (docs/public/editor/index.html).

Changes

• HTML: Removed Copy button element and feedback toast notification
• CSS: Removed .copy-feedback styles (~16 lines)
• JavaScript: Removed copyBtn variable, event handler, and state management (~30 lines)

Visual

Header toolbar now shows: Auto-compile toggle → Compile button → Theme toggle

Users can still copy output via native browser selection (Ctrl+C).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: /opt/hostedtoolcache/node/24.13.0/x64/bin/node node /home/REDACTED/work/gh-aw/gh-aw/docs/node_modules/.bin/astro dev (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

The currentYaml variable is no longer used after removing the Copy button functionality. This variable was only read by the removed copy event handler. Consider removing the currentYaml variable declaration (line 378) and all its assignments (lines 532 and 553) to avoid maintaining unused state.
