See where it says "tmpfs"? The /run file system is entirely ephemeral,
existing only in memory while the system is running.
If you want to re-create something in /run at boot time, you'll need to
set up a task to do so, either by creating a systemd unit, or perhaps by
using rc.local (since this is a ridiculously small and simple one-shot
task, where a whole systemd unit would be overkill, rc.local is fine).
Or, if you prefer, you could add "create the directory in /run" to
your application's start-up code.
