Function cli_uninstall_report_leftover_installer

src/cli/cli.c:11327–11366

Report — never delete — the updater script sitting next to the binary. * * install.sh/install.ps1 copies itself beside the executable so `update` has * something to hand off to. Uninstall does NOT remove it, deliberately: we * cannot prove we own that file. The user may have put their own copy there, it * may be a symlink into a checkout, or a package manager may manage it. Deleting * a file

 * shouldn't. Telling the user the exact path costs one line and leaves the
 * decision with them. */
