fix: address concurrency adapter feedback - bulk operations and upfront checks - Check all zero limits upfront before acquiring any slots - Use true bulk operations for V2 limit acquisition (single call) - Optimize decrement to use bulk reads and bulk decrements - Fix batching in lease search (no offset support in read_active_lease_ids) These changes prevent partial acquisitions and reduce rollback complexity as identified in review feedback.
