pub fn quit(&mut self) {
		self.quit = Some(QuitManner::Abort);
	}
Shut down the Watchexec instance immediately.

This will kill and drop all jobs without waiting on processes, then quit.

Use `graceful_quit()` to wait for processes to finish before quitting.

The quit is initiated once the action handler returns, not when this method is called.
