/**
 * Scene evaluation turn plugin (ADR-149, ADR-186).
 *
 * Evaluates scene begin/end conditions each turn. Runs after NPC turns
 * and state machines, before daemons/fuses (priority 60).
 *
 * For each registered scene:
 * - If state='waiting' and begin() returns true → activate, emit scene_began,
 *   then invoke the scene's onBegin reaction (ADR-186)
 * - If state='active' and end() returns true → end (or reset if recurring),
 *   emit scene_ended, then invoke the scene's onEnd reaction (ADR-186)
 * - If state='active' → increment activeTurns
 *
 * scene_began / scene_ended are emitted as observable facts (perception,
 * tooling, transcripts). Author-visible reactions come from the typed
 * onBegin/onEnd callbacks, translated here into game.message events — the
 * event the prose pipeline renders — so reactions are visible by construction
 * (ADR-186).
 *
 * Public interface: SceneEvaluationPlugin (TurnPlugin implementation).
 * Owner context: @sharpee/engine — turn cycle
