CVarify meteor behavior (#29030)

* CVarify meteor behavior

* Cache value to reduce CVar calls, hook into OnValueChanged

* _cfg is still null at construction time, fixed by just making it set up on Started instead

* Invoke immediately! Learning more every step of the way.

* Move cached value initialisation to Initialize call

* Add explicit supercall
