Add smoke test for anonymous chat access

[Copilot]

Adds a smoke test to validate anonymous chat functionality by enabling chat.allowAnonymousAccess, sending a message, and verifying a response is received.

Changes

• test/automation/src/chat.ts: Added waitForResponse() method with selectors for response elements (.interactive-response) and completion state (:not(.chat-response-loading))
• test/smoke/src/areas/chat/chatAnonymous.test.ts: New test that:
  • Enables chat.allowAnonymousAccess setting
  • Opens chat view and sends a message
  • Waits for response completion
• test/smoke/src/main.ts: Registered new test (Electron-only, matching existing chat tests)

Example usage

// In automation tests
await app.workbench.chat.sendMessage('Hello');
await app.workbench.chat.waitForResponse();

test/automation/src/chat.ts:54

• The waitForResponse method passes the retryCount parameter to waitForElement, but this parameter could be undefined. While waitForElement has a default value of 200 for retryCount, it's better to be explicit about the default behavior or document that undefined will use the default. Consider adding a comment explaining this parameter or providing a default value in the method signature.

	async waitForResponse(retryCount?: number): Promise<void> {

		// First wait for a response element to appear
		await this.code.waitForElement(CHAT_RESPONSE, undefined, retryCount);

		// Then wait for it to complete (not loading)
		await this.code.waitForElement(CHAT_RESPONSE_COMPLETE, undefined, retryCount);
	}
