Multiple Role Tokens not removed

Have [[Gylwain, Casting Director]] and [[Anointed Procession]] in play.
Cast a creature spell to trigger Gylwain, creating a Monster role token.
Anointed Procession creates a duplicate role token attached to the creature but keeps the initial role token.

Expected behavior: First role token should be destroyed.
```
303.7a If a permanent has more than one Role controlled by the same player attached to it, each
of those Roles except the one with the most recent timestamp is put into its owner’s graveyard.
This is a state-based action.
```

Start by reproducing the Gylwain, Casting Director and Anointed Procession scenario described in the issue, then trace the role-token handling and state-based-action logic. Done means the older of multiple same-player Roles is put into its owner’s graveyard while the most recent Role remains attached.
