/**
 * Realtime pub/sub — per-project managed event channels.
 *
 *   GET    /realtime/status?projectId=         — availability
 *   GET    /realtime/channels?projectId=       — list active channels
 *   POST   /realtime/channels                  — reserve a channel name
 *   DELETE /realtime/channels/:channelName     — free a channel
 *
 * Consumers open managed realtime connections from their app; this SDK
 * module only manages the channel registry (create / list / delete).
