// SceneSession.swift
// Holds references to the active scene's CPInterfaceController, CPWindow,
// CarPlayMapViewController, and the three feature handlers.
//
// `static var current` is the access point for ExpoCarPlayModule's
// AsyncFunctions — an honest "the one connected scene at a time"
// accessor. When multi-scene support (Dashboard, Cluster) lands later,
// it becomes additive: SceneSession.dashboard: SceneSession? etc.
//
// Lifecycle: CarPlaySceneDelegate constructs this in didConnect and sets
// SceneSession.current = nil in didDisconnect. The latter deallocates
// the handlers + view controller, which is what fixes the
// state-leak-across-disconnect bug that motivated D1.
//
// See: docs/superpowers/specs/2026-05-16-di-rework-design.md
