/**
 * Logging Stream Registry
 *
 * Manages RPC subscriptions for streaming logs from server to connected clients.
 *
 * Purpose:
 * - Registers client subscriptions to model/SDK log streams
 * - Routes log messages to subscribed clients via RPC
 * - Buffers logs during model loading (before client subscribes)
 * - Manages stream lifecycle (subscribe/unsubscribe)
 *
