settings live in one registry, and the net drain starts to peel

- the CVars are one engine-side table that outlives every interface reload: a change fires its observer, the eight latched rows wait for RestartGx, and /console gains set, cvar_reset, cvar_default, cvarlist and help (2303)
- every push into the interface runs in one feed phase after the net drain and before the tick, held by a structural test on the built schedule (2304)
- subsystems own their packet handlers, dispatched in packet order; the auction house is the first family out of the 273-arm drain (2305)
