Flight-test the fly

Tests the fly's T4/T5 to HS/VS to DNa02 steering pathway as an aircraft yaw damper, the way flight-control laws are tested: frequency response, loop margins, MIL-spec Dryden turbulence and neuron loss, all against degree- and sign-preserving shuffles, the bare airframe and a classical damper. Phase 1 is in. At 1 Hz the real wiring ranks first of twenty, with coherence 0.980 against a shuffle median of 0.31 and gain 0.666 against 0.075 Hz per deg/s. The plant is JSBSim's c172x. Later phases are re-running after an outside audit; FINDINGS.md marks every line as measured, cited or unchecked.
