Publish SOXL crisis response plugin artifacts

[Pigbibi]

Summary

• publish crisis_response_shadow artifacts for both TQQQ and SOXL via workflow matrix
• use SOXX/SOXL as the SOXL plugin benchmark/attack symbols
• keep plugin mode shadow-only and add separate SOXL GCS override support
• add SOXX realized volatility fields to the SOXL backtest signal history so research and live indicators stay aligned
