Restore sources box: expand by default so it's visible at the bottom of AI messages

[Copilot]

buildSourcesBubble was never removed by the file-attachments PR, but the sources list started with class="sources-list hidden" — requiring a click to reveal. This made the box appear absent.

Change

In buildSourcesBubble, start the list expanded instead of collapsed:

-  var list = document.createElement('div'); list.className = 'sources-list hidden';
+  var list = document.createElement('div'); list.className = 'sources-list';
   ...
-  var chev = hdr.querySelector('.chev'); var open = false;
+  var chev = hdr.querySelector('.chev'); var open = true;
+  if (chev) chev.classList.add('open');

Sources are now immediately visible below the AI message when the LLM uses web_search. Click-to-collapse is preserved.

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:

• cdn.jsdelivr.net
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node (dns block)
• fonts.googleapis.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node (dns block)
• https://api.github.com/repos/sriail/MacAI/git/trees/0fd1ab74771e444a9e67cb6c6f62901ea75a4499
  • Triggering command: /usr/bin/python3 python3 (http block)
• https://api.github.com/repos/sriail/MacAI/git/trees/ab7d85cbaea044cdd93538a6055d162fffd7fc9e
  • Triggering command: /usr/bin/python3 python3 -u bin/WALinuxAgent-2.15.1.3-py3.12.egg -collect-logs (http 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)
