New REPL: Prompt overwrites previous output on line wrap

[ImFeH2]

Bug report

Bug description:

When output doesn't end with newline and the next prompt appears mid-line, typing input that causes line wrapping makes the prompt overwrite previous output.

Steps to Reproduce

Then type enough characters, the content before the prompt will be overwritten.

Additionally, pasting causes display formatting errors

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux

I think this issue occurs because the REPL assumes each line has a maximum width equal to the terminal width.
Possible solutions could be supporting variable line widths or preventing mid-line prompts.

while trying to recreate the bug found another weird bug in windows terminal (python V3.13.3)

STOUT's last line is prented in next prompt area (tried with larger number and it always happens only with the last line)
