Remove incorrect @SuppressWarnings("unused") annotation

[Copilot]

The approvalResponse variable was incorrectly annotated with @SuppressWarnings("unused") despite being used in the subsequent session.sendEvent() call.

Changes:

• Removed the suppression annotation from the approvalResponse variable declaration in MCPSample.java (line 394)

// Before
@SuppressWarnings("unused")
MCPApprovalResponseRequestItem approvalResponse =
    new MCPApprovalResponseRequestItem(approvalId, approved);

session.sendEvent(new ClientEventConversationItemCreate().setItem(approvalResponse))

// After
MCPApprovalResponseRequestItem approvalResponse =
    new MCPApprovalResponseRequestItem(approvalId, approved);

session.sendEvent(new ClientEventConversationItemCreate().setItem(approvalResponse))
