/**
 * Gateway initialization for Discord, Slack, and Telegram.
 *
 * Extracted from cli/commands/start.ts to keep the orchestrator thin.
 * All logic and function signatures are unchanged.
 *
 * Responsibilities:
 *   1. Creates `gateways` array for cleanup tracking
 *   2. Constructs `gatewayMultiAgentConfig` and `gatewayMultiAgentRuntime` objects
 *   3. Initializes Discord gateway (if config.discord enabled):
 *      - Normalizes guild config via normalizeDiscordGuilds()
 *      - Creates DiscordGateway instance
 *      - Creates gatewayInterface object with sendMessage/sendFile/sendImage
 *      - Calls agentLoop.setDiscordGateway(gatewayInterface)
 *      - Wires multi-agent handler's gateway tool executor
 *      - Calls discordGateway.start()
 *   4. Initializes Slack gateway (if config.slack enabled):
 *      - Creates SlackGateway instance
 *      - Creates slackGatewayInterface
 *      - Calls toolExecutor.setSlackGateway(slackGatewayInterface)
 *      - Calls slackGateway.start()
 *   5. Initializes Telegram gateway (if config.telegram enabled):
 *      - Creates TelegramGateway instance
 *      - Wires toolExecutor.setTelegramGateway() and agentLoop.setTelegramGateway()
 *      - Calls telegramGateway.start()
