Add install-remote.sh, which fetches the latest release and runs its
install.sh so setup no longer needs a git clone. The popup now probes
the native host with a "ping" action on open and, if it's not
registered yet, shows the one-liner (with copy-to-clipboard) instead
of the auto-capture toggle -- so a Web Store install can be completed
end-to-end by clicking the extension icon and pasting one command.
Chrome's own "Ask where to save each file" setting shows a native
picker before the extension can ever intercept the download, and no
extension API can read or suppress it -- surface this clearly in
install.sh, the README, and a popup shortcut instead of leaving it
buried as a footnote.
Also fixes silently missing "download complete" notifications: KGet
only fires its own finished-notification if a transfer was observed
in a non-finished state at least once, so small/fast downloads that
complete before that first observation never get one. The native
host now drives its own notification via notify-send, polling actual
transfer progress instead of relying on KGet's internal check, and
install.sh disables KGet's own notification to avoid duplicates.
