implement cron scheduler worker and WebSocket notifications ## Issues Addressed - #115: Cron scheduler worker - #116: Cron WebSocket notifications ## Changes ### CronSchedulerService (cron.scheduler.ts) - Polls CronSchedule table every minute for due schedules - Executes commands when schedules fire (placeholder for MoltBot integration) - Updates lastRun/nextRun fields after execution - Handles errors gracefully with logging - Supports manual trigger for testing - Start/stop lifecycle management ### WebSocket Integration - Added emitCronExecuted() method to WebSocketGateway - Emits workspace-scoped cron:executed events - Payload includes: scheduleId, command, executedAt ### Tests - cron.scheduler.spec.ts: 9 passing tests - Tests cover: status, due schedule processing, manual trigger, scheduler lifecycle ## Technical Notes - Placeholder triggerMoltBotCommand() needs actual implementation - Uses setInterval for polling (could upgrade to cron-parser library) - WebSocket rooms use workspace:{id} format (existing pattern) ## Files Changed - apps/api/src/cron/cron.scheduler.ts (new) - apps/api/src/cron/cron.scheduler.spec.ts (new) - apps/api/src/cron/cron.module.ts (updated) - apps/api/src/websocket/websocket.gateway.ts (updated) --- apps/api/src/cron/cron.module.ts | 10 +- apps/api/src/cron/cron.scheduler.spec.ts | 127
