Add analysis scripts for the 10-vs-20 flow-matching ODE-step ablation on the
energy-conservation PoC predict outputs:
- compare_ode_steps_energy_conservation.py: per-event energy-budget table +
20-step plots and the 10-vs-20 overlay.
- compare_ode_steps_kl.py: per-step marginal KL(real||gen) per target dim over
fixed shared bins, so the two runs are directly comparable dim-by-dim.
Also commit export_energy_conservation_poc.py (the baseline event-level budget
export) and repoint validation.ipynb at the PoC predict file at sample_frac=1.0.
