Module state_scorer 

StateActionScorer: encounter’s ActionScorer impl backed by an EncounterArgumentationState.

The scorer composes:

1. An inner ActionScorer<P> that produces base scores.
2. A reference to a live EncounterArgumentationState.

After the inner scorer runs, each scored affordance is amplified by boost * state.is_credulously_accepted(arg_id) where the argument id is looked up from the affordance’s forward-index key. Affordances with no seeded argument receive no boost (inner score unchanged).

This gives the proposer bias: actions whose own argument is credulously acceptable at the scene’s current β get boosted, making the scene self-consistent with the argumentation state. The per-responder gate is orthogonal and lives in crate::state_acceptance::StateAcceptanceEval.
