// Delete move operations to prevent accidental moves of SchedulerItem objects.
// This is intentional because:
// 1. SchedulerItem contains a dynamically allocated name that requires careful ownership management
// 2. The scheduler only moves unique_ptr<SchedulerItem>, never SchedulerItem objects directly
// 3. Moving unique_ptr only transfers pointer ownership without moving the pointed-to object
// 4. Deleting these operations makes it explicit that SchedulerItem objects should not be moved
// 5. This prevents potential double-free bugs if the code is refactored to move SchedulerItem objects
// Delete move operations: SchedulerItem objects are only managed via unique_ptr, never moved directly
