Replace the return-0 stubs with the real functions:
- ResolveLink (FUN_00417ab4) = SubsystemConnection::Resolve (two-level deref of the
plug's bound link); an unbound plug resolves to 0, the authentic no-source branch.
- FindLinkedSubsystem (FUN_0041bf44) = GetAttributePointer(index) via the engine
Simulation attribute-index system (the cooling-loop master at slot 3).
- IsGeneratorDerived (FUN_0041a1a4) = the real IsDerivedFrom(PoweredSubsystem
ClassDerivations 0x50f4bc) via a new powersub.cpp bridge BTIsPoweredSubsystem
(shared with the aux-screen filter) -> the generator stateLamp now builds.
So the cooling/power/voltage connections resolve real data when the plug is bound,
instead of always reading 0. Build clean.
