Add command scheduling feature

[Copilot]

Introduces a lightweight periodic task scheduling infrastructure built on the existing ITimerFactory abstraction.

Changes

• IScheduledTask — interface for a named, periodic task (Name, Interval, ExecuteAsync)
• ICommandScheduler — interface exposing Register(IScheduledTask) + Start(CancellationToken)
• CommandScheduler — implementation that allocates one ITimer per task, dispatches execution to the thread pool, absorbs per-task exceptions, observes Task.Run faults via ContinueWith, and stops/disposes all timers on DisposeAsync
• Guards against double-start and post-Start registration

await using CommandScheduler scheduler = new(timerFactory, logManager);

scheduler.Register(new MyPeriodicTask(interval: TimeSpan.FromMinutes(5)));
scheduler.Start(cancellationToken);
