Description
The feature request came from xonsh shell - https://github.com/xonsh/xonsh/discussions/6044
When we call prompt() method we can't set default buffer suggestion. But it would be very helpful for AI suggesters or extracting next command from history, etc.
The minimal example of use case:
prompt> echo 1
prompt> echo 2
prompt> echo 3
prompt> echo 1
prompt> <cursor>echo 2 # Here `echo 2` is the suggestion (grey text).

Research direction
Start with the prompt() call in xonsh's ptk_shell/init.py and the default buffer suggestion behavior referenced in prompt_toolkit's buffer.py. Trace how prompt() creates or configures its buffer, including the empty-prompt and suggestion argument cases. Done means callers can provide a grey default suggestion for the cursor without inserting it as entered text.
