[codex] Sync TQQQ risk diagnostics

[Pigbibi]

Summary

• Sync TQQQ risk-control diagnostics across snapshot, mapper, and notification paths.
• Preserve 5-day annualized volatility deleveraging, macro-risk, crisis-defense, and market-regime audit fields.
• Align dependency pins for QuantPlatformKit / UsEquityStrategies where applicable.

Validation

• Targeted py_compile checks passed for modified Python files.
• Targeted signal snapshot tests passed for all four platform repos.
• Targeted mapper tests passed where dependencies were available; LongBridge mapper field pass-through was verified with a lightweight strategy_registry stub because local pandas is not installed.
• git diff --check passed for all four repos.
• Cross-platform critical field audit passed.
