…ngine updates

- Move GramSetup/VaryingCoefSetup/calculate_weights/vc_stability_total_lr/
  taylor_microscale/resolve_vc_modes (+helpers) out of supplementary.py into
  operators/common/stability.py; repoint consumers (globals stay lazy ->
  circular-import-safe).
- Uncapped sum_noeps score (Var(gamma_0)+NC_deb)/gamma_0^2; drop vc_score_formula flag.
- _cached_vc_score reuse: fitness sums the sparsity pass's per-term scores
  instead of rebuilding the full-N Gram.
- main_structures: Equation.__eq__ length-guard. Docstring/comment cleanup
  (stale patch/radius framing, test citations).
- Accumulated engine WIP: _loop_stats timers, MOEA/D sector-order shuffle,
  mutation/RPS uniqueness dedup.

… pic data-prep

- configs/wave.yaml: degenerate-quadratic truth_alternative (u_xx^2 = 48.68
  u_xx u_tt - 591.98 u_tt^2) -- an exact algebraic consequence of the wave
  equation EPDE discovers; credited like the burgers_inviscid similarity form.
- thesis_metrics/aggregate/ablation_aggregate/runner/profile_loop_stats/run:
  metric, aggregation, profiling updates.
- New analysis scripts (vcoef stability/regularizer diagnostics + AC instability figs).
- projects/pic/data/*: per-system data-prep tweaks.
