/**
* @deprecated This function is no longer called and should not be used.
*
* REASON FOR DEPRECATION:
* - Keyword-based detection causes false positives when backend logs contain
* words like "Installing", "Updating", "Syncing" during normal operation
* - Checking file system on every backend log line is inefficient
* - Installation is now only handled through explicit installation flow in createWindow
*
* This function is kept for backwards compatibility but is not invoked anywhere.
