create_quest_batch.md

Description

Creating multiple quests requires separate transactions, which is expensive and slow during large game deployments.

Expected Behavior

Admins or quest creators should be able to create multiple quests in a single transaction.

Proposed Changes

function createQuestBatch(QuestParams[] calldata quests) external;

Acceptance Criteria

• Batch creation works for arrays of any valid size
• Gas usage is measurably lower than equivalent individual calls
• Tests cover batch success and partial failure scenarios
