Pull request overview

Improves agent tool-call status rendering in the chat UI by ensuring error tool-call updates display meaningful text (preferring toolCall.error and falling back to progressMessage), and adds UI tests to validate the behavior.

Changes:

• Relaxed the early-return guard in BaseTurnWidget.appendToolCallStatus to allow processing error-only tool-call updates.
• Updated error status handling to set the status label text from toolCall.error (fallback to progressMessage).
• Added a new UI test suite covering multiple error status scenarios and overwrite behavior.

    String status = toolCall.getStatus().toLowerCase();
    // Require a non-blank progressMessage for non-error events. For error events,
    // also accept a non-blank `error` field as the displayable text.
    boolean isError = "error".equals(status);
    if (StringUtils.isBlank(toolCall.getProgressMessage())
        && (!isError || StringUtils.isBlank(toolCall.getError()))) {
      return;

    // Check if this is a run_subagent tool call
    if ("run_subagent".equalsIgnoreCase(toolCall.getName())) {
