Added 'set +o history' to prevent the trace eraser commands from being re-added to history.
Changes:
• Disable history recording before cleaning (set +o history)
• Clear in-memory history with history -c
• Write empty history with history -w
• Added note to run 'exec bash' for clean shell
• Prevents script commands from being saved
This ensures the last 10 entries are properly removed and the cleanup commands themselves don't get recorded.
