Update engine overwrites local shell configurations

[shantoshdurai]

The update engine (update_dusky.sh) uses git reset --hard during synchronization, which reverts local modifications to ~/.zshrc if they haven't been committed. Specifically, it commented out ~/.local/bin from the PATH and removed custom aliases like killandroid.

Proposed fix: The engine should detect uncommitted changes to tracked files like .zshrc and either commit them automatically or warn the user before performing a hard reset.

its intentional, and for a good reason, it doesnt overwrite, it backs up user modifiend files to documetns/dusky_backups
