chore: fix 'false positive' data race detection in Id/Number default init (#867) 
A step's `Id` & `Number` are potentially initialized in different goroutines on matrix evaluations; this change ensures they're initialized before execution fans out to multiple goroutines.  There doesn't seem to be any functional impact of this data race for end-users.

Where `Number` was previously initialized, a runtime error was added to ensure that the behavior is the same.

`ID` data race:
