Subject: [PATCH] Fix Subaru init parameter MISRA compliance

Normalize a same-type local copy instead of modifying the input parameter.
Existing safety logic and all 34 paired firmware artifacts remain byte-identical.
Validated 67 debug and 67 release native cases; refresh source inventory receipt.
