Mech milestone phase 2: reconstruct Sensor (first roster leaf) -- vertical slice complete

Sensor : public PoweredSubsystem -- the radar/targeting subsystem, using the SURVIVING 4.10 interface (CODE/BT/BT/SENSOR.HPP) with a reconstructed SENSOR.CPP body (from BT411 decomp). Ctor chains PoweredSubsystem, inits radarPercent/ selfTest/badVoltage, and installs the per-frame performance unless the owner is a replicant (owner->GetInstance() != ReplicantInstance -- the clean form of the binary's (flags & 0xC) != 4). Statics, dtor, TestClass/TestInstance, ResetToInitialState, TakeDamage, DeathReset real; SensorSimulation (per-frame radar) + CreateStreamedSubsystem staged. Completes the first full vertical slice of the subsystem roster, all compile-verified: MechSubsystem -> HeatableSubsystem -> HeatSink -> PoweredSubsystem -> Sensor. The hierarchy backbone is proven; remaining leaves (Generator, Gyro, Torso, HUD, Myomers, weapons) follow the same pattern. BT: 27 ok; tree links clean.
