Executing "Ask Copilot about the Azure Activity Log" command shows misleading timeout error when Copilot Chat is not installed

[v-ruizh]

OS: Win 11 x64
Build Version: v0.12.4

Repro Steps:

1. Install Azure Resources extension in VS Code.
2. Ensure GitHub Copilot Chat (GitHub.copilot-chat) extension is NOT installed.
3. Sign in to an Azure account.
4. Populate Azure Activity Log by performing any Azure operations.
5. Click "Ask Copilot about the Azure Activity Log" icon in Azure activity window.

Expect:
If the required dependency (GitHub Copilot Chat extension) is not installed, the extension should detect this and prompt the user to install it before attempting to execute the command.

Actual:
The following error message is shown.

More Info:
The "Restart" button is provided but does not resolve the issue.

Does this only repro when the activity log LM tool is supposed to trigger, or does it also happen with other dialogues with Copilot chat?

No, this issue is not scoped to the Activity Log LM tool invocation.
It also reproduces when executing the "Ask Copilot" command for a Docker image, indicating that it can occur in other Copilot Chat dialogues as well.

The agent encountered an error and was unable to start working on this issue: Before you can use Copilot cloud agent, you need to pick a "Usage billed to" option in your Copilot settings. Update your settings, then try again. (Request id: 6340:7872E:1404DA65:1459CC96:69DD656D)

From Jing's fix markdown:

Add error handling — Wrap the executeCommand calls in a try-catch and show a user-friendly message if Copilot Chat is unavailable.
Check Copilot Chat availability — Before executing, verify that the workbench.action.chat.open command is registered and that a Copilot Chat provider is active.
Investigate mode: 'agent' compatibility — Verify that the mode: 'agent' parameter is supported in the minimum VS Code version the extension targets.
