Fixes #2017

Description
This PR fixes a display artifact on Linux/WSL where the status message "Analyzing data in general mode" would not fully overwrite the previous text on the line, resulting in corrupted output like modetream instead of mode.

Technical Details
The mprint function in src/lib_ccx/utility.c was updated to explicitly send the clear-line sequence (\033[K) when handling a carriage return (\r) on Linux. This ensures the line is wiped clean before the new status is printed, matching the behavior expected on other platforms.

Verification

Tested on WSL (Ubuntu).
Confirmed that the "modetream" artifact is gone and the status line updates cleanly.
