jgrusewski bfbaea2661 spec(ml-backtesting): real-LOB integration design ...

Greenfield LOB simulator + execution policy + backtest harness inside
existing ml-backtesting crate. Turns the AUC predictor into a P&L
producer at IBKR+Scaleway latency profile (100ms baseline).

Key design decisions:
- Reuse trainer's MultiHorizonLoader, Mbp10RawInput, snap_feature_assemble
  cubin, CfcTrunk captured graph verbatim (zero train-vs-deploy skew).
- Per-horizon ISV-Kelly + adaptive WeightedByRealizedSharpe aggregator
  (no static horizon mask; policy self-shifts capital).
- Block-per-backtest CUDA (32 threads/warp/block), ~1.4 KB shared mem.
- Three captured graphs (perception, step-event, decision); host branches
  only between captures.
- Mapped-pinned for all CPU/GPU buffers (hard requirement per
  feedback_no_htod_htoh_only_mapped_pinned).
- Three validation rings: N=1 bit-exact fixtures, trainer-parity check,
  N>1 invariant fuzz; production-day replay as Ring 3.

Single binary fxt-backtest with run + aggregate subcommands. No new
crates; extends existing ml-backtesting alongside barrier_backtest.
