Module trade_security 

Stable API — trade-side security code shape and sec-market derivation. Used by futu-trd and trade-write domain without introducing reverse runtime/domain dependencies. Trade-side security code shape and market derivation helpers.

These pure rules sit below both SDK/runtime crates and trade-domain crates: futu-trd needs them for public SDK projection, while trade-write domain keeps compatibility re-exports for write-path policy.
