Vortex-Gated Mixture of Experts: Symbolic, Zero-Parameter Routing via TERA Projection

Vortex-Gated MoE (VG-MoE): a drop-in MoE gate using a deterministic, closed-form TERA projection with zero gate parameters. This revision adds a Reference Implementation & Verification note to Data Availability: the paper's falsifiable claims are now numerically verified in the open-source harmonic-engine package (tests/test_new_math.py, passing on CPU). The VortexGate routing math and HeartScale alignment scalars are exercised by the harmonic-engine suite.
