Subject: [PATCH] dracut-ng: enhance rd.cmdline=ask prompt visibility and
 robustness

The current "rd.cmdline=ask" prompt is very easy to miss during the boot
process, as it's just a single line of text that often gets buried among
other kernel messages.

It improves the user experience by:
- Adding a high-visibility 80-column ASCII banner to clearly signal that
  input is required.
- Refining the text to clarify that both kernel and install program parameters
  are accepted.
- Implementing a temporary 'trap' for SIGINT (Ctrl+c). Since the 'd' key is
  physically close to 'c' on most layouts, it's easy to accidentally kill
  the script when trying to send EOF (Ctrl+d).
- Using shorter, consistent sleep intervals for a smoother rendering of the
  banner.

Old prompt:
Enter additional kernel command line parameter (end with ctrl-d or .)

New prompt:
    ========================================================================
(o<                                                                          >o)
//\                        INPUT REQUIRED !!!                                /\\
V_/_                                                                        _\_V
    ========================================================================

 Enter additional kernel command line, or install program, parameters.
 End with a period "." or Ctrl+d in a new line:
