preserve scrollback buffer [feature request] #165
Description
Under Linux, when the screen is cleared via clear, the scrollback buffer also gets cleared. This should be retained, such as via the -x option:
$ man clear
Usage: clear [options]
Options:
-T TERM use this instead of $TERM
-V print curses-version
-x do not try to clear scrollback
This has the advantage that the initialization status messages are preserved. For example,
$ python -m mcp_client_for_ollama.cli

In this example, my pubmed configuration got messed up, so it is good to preserve the error messages.
This can be implemented as follows:
$ git diff mcp_client_for_ollama/client.py
...
import os
+import platform
import sys
...
def clear_console(self):
"""Clear the console screen"""
- os.system('cls' if os.name == 'nt' else 'clear')
+ os.system('cls' if os.name == 'nt' else
+ 'clear -x' if platform.system() == 'Linux' else
+ 'clear')
...
