Function composablePolicyRecipe

Build the createComposablePolicy argument bundle from a forward config

• optional validation recipe outputs, applying the enforcement posture (throw security-critical, warn economic gaps).

Determines the settlement shape from the forward config:

• act mode: forward enabled + outputMint == PublicKey.default() — no fungible output; post_validation is the only delivery backstop.
• deliver-transform: forward enabled + outputMint != inputMint — forward swaps input → output before delivery.
• deliver-no-transform: forward disabled OR same-mint — direct sweep.

Pure except for console.warn side-effects on economic gaps.
