/**
 * Scheduler initialization for MAMA OS.
 *
 * Extracted from cli/commands/start.ts to keep the orchestrator thin.
 * All logic and function signatures are unchanged.
 *
 * Responsibilities:
 *   initCronScheduler:
 *     1. Creates CronWorker + EventEmitter (for gateway routing)
 *     2. Creates CronScheduler and wires executeCallback to CronWorker
 *     3. Loads cron jobs from config.scheduling.jobs
 *
 *   initHeartbeat:
 *     1. Creates HeartbeatScheduler (interval, quiet hours, Discord notify)
 *     2. Wires scheduler + heartbeat into HealthCheckService
 *     3. Starts periodic health-warning interval (every 5 minutes)
 *     4. Creates TokenKeepAlive and starts it
