iven	5d6e1dc394	feat(core): implement optimistic locking across all entities ... Add VersionMismatch error variant and check_version() helper to erp-core. All 13 mutable entities now enforce version checking on update/delete: - erp-auth: user, role, organization, department, position - erp-config: dictionary, dictionary_item, menu, setting, numbering_rule - erp-workflow: process_definition, process_instance, task - erp-message: message, message_subscription Update DTOs to expose version in responses and require version in update requests. HTTP 409 Conflict returned on version mismatch.	2026-04-11 23:25:43 +08:00
