Extends bindAll/bindAllProduction/bindAllDevSeed to accept BindAllDeps and thread realtime + realtimeRegistry as the 6th and 7th positional args into each per-feature binder. Adds bindRealtimeBridge stub (empty allowlist in v1). bindAll accepts optional deps with InMemoryRealtimeBroadcaster fallback so existing page-level callers stay type-safe.
