Add resume-on-new-instance guide

Refresh code/ with latest BLT-Reasoner sources (post-campaign)

HANDOFF v3: 77.5% via bottleneck-as-regularizer at inference

BREAKTHROUGH: same GRPO ckpt eval without bottleneck = 77.5% GSM8K AR (vs 52.5% with bottleneck)

Per-CoT-step multi-objective experiment

GRPO Phase C from Options 1+3 ckpt

GRPO Phase C from Options 1+3 ckpt

EXP 1+3: AR n=200 K=16 ablation result (51% normal, delta_zero=50.5pp)

EXP 1+3: TF n=200 K=16 ablation result (delta_zero=23pp)

EXP: Options 1+3 (full-y InfoNCE + MLP projector)
