Subject: [PATCH] fix(opencode): use toLowerCase for Devstral model detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

toLocaleLowerCase is locale-sensitive and can break model-id matching
in Turkish locale (I -> ı). Every other model-id check in this file
already uses toLowerCase.

Closes #33108
