Refresh production baseline numbers in the README

The baseline table and promotion evidence still carried pre-primary-target-floor
figures. Re-derived every number from the 2026-07-11 run, the first baseline
measured after the 20% probability floor pruned lottery targets (1,428 -> 1,089
qualified).

The promotion evidence table also claimed the promoted book beat legacy on
"CAGR, Sharpe, and drawdown". That no longer holds: legacy residual 80 + hold
now has the shallowest drawdown (-15.8% vs -21.4%). Production still wins on
Sharpe, so the promotion stands, but the text now says so honestly rather than
implying a clean sweep.

Also documents the primary-target reach-probability floor in the gate
description, which shipped in c7a198b/8f41143 but never reached the README.

+Read the top three honestly: the production book wins on Sharpe, not on every axis. The 80/20 vol tilt buys ~2pp of CAGR over the legacy residual-only book but costs ~6pp of drawdown, and the ATR trail hands part of that drawdown back. If drawdown ever matters more than risk-adjusted return here, legacy residual 80 + hold is the row to revisit.
 
 The conclusion is not "trade high volatility alone." Keep residual momentum as the entry gate, use realized volatility only as a small ranking tilt, and add the ATR trail as defensive exit discipline.
