Simplify convoluted nested condition logic in text handler

[Copilot]

Descripción

Refactors nested conditional logic in handleText that was flagged as convoluted and difficult to understand. The original implementation had a confusing double-nested condition where the outer checked cmd.NewLine || cmd.Content == "" and the inner checked cmd.NewLine || (cmd.Content != "" && !cmd.NewLine).

Before:

if cmd.NewLine || cmd.Content == "" {
    if cmd.NewLine || (cmd.Content != "" && !cmd.NewLine) {
        if err := printer.PrintLine(cmd.Content); err != nil {
            return err
        }
    }
} else {
    if err := printer.Print(cmd.Content); err != nil {
        return err
    }
}

After:

if cmd.Content != "" {
    if cmd.NewLine {
        if err := printer.PrintLine(cmd.Content); err != nil {
            return err
        }
    } else {
        if err := printer.Print(cmd.Content); err != nil {
            return err
        }
    }
}

The refactored version makes the logic explicit: skip empty content, use PrintLine for newline-terminated content, otherwise use Print. Style reset logic remains unchanged and executes in all cases.

Pull Request Overview

This PR simplifies the text printing logic in the handleText function by removing confusing nested conditional statements and replacing them with a clearer, more maintainable structure.

• Refactored the text printing conditional logic from nested if-statements to a straightforward structure
• The new implementation checks if content exists first, then decides whether to print with or without a newline based on the NewLine flag

This refactoring changes the behavior when cmd.Content is empty but cmd.NewLine is true. The previous code would print a blank line in this case, but the new code skips printing entirely. While the new logic is cleaner and more intuitive (using FeedCommand for blank lines), this behavioral change could affect existing code or JSON documents that rely on printing blank lines via text commands with empty content. Consider whether this breaking change is intentional and if it requires documentation or a migration guide.
