- Performance: O(1) movement with conflict detection
Contracts:
Preconditions:

- User has accessibility permissions
Postconditions:
- Macro exists in target group OR error with rollback info
- Source group no longer contains macro on success
- System state is consistent (no partial moves)
Invariants:
- Macro can only exist in one group at a time
- All movements are audited and logged
