Kill the app at high RAM, instead of trying to throttle it first

Browse source 
Well, sitting at the `MemoryHigh` limit still grinds the app to a halt
anyway, lmao. I guess it's a feature designed for well-behaved processes
and not for outright leaking ones?

Let's try just having systemd basically reset the app regularly when the
RAM hits a certain threshold. I think that's what this config will do,
we'll find out!

; Try not to go over 1GB of RAM, and kill the app at 1.2GB.
MemoryHigh=1G
; Kill the app at 1.2GB of RAM.
; NOTE: It's generally recommended to pair this with a `MemoryHigh` setting, to

; our app has a memory leak that causes it to always keep growing - and then the

MemoryMax=1.2G
; Some security directives, adapted from Akkoma's service file, they seem like sensible defaults!
