fix: 6 concerns in Cross-Pollinated Branch Intelligence spec
1. Variable Selection: static → input-dependent bottleneck (true TFT VSN)
2. Q Attention: add direct gradient via Expected SARSA target integration
3. Liquid Tau: modulates IQL scales via separate liquid_mod[4] buffer
4. Selectivity: per_sample_loss proxy (per-sample grad norms infeasible at 32GB)
5. GLU gate: zero-init W_gate/b_gate → sigmoid(0)=0.5 (stable start)
6. Weight layout: updated for 8 VSN bottleneck matrices (indices 26-33)
NUM_WEIGHT_TENSORS: 26 → 42. Total new params: ~297K.
