Dify 1.13.2

This patch release fixes several critical regressions and stability issues introduced in v1.13.1, including:

• a severe regression in prompt message transformation that caused multiple LLM-plugin invocation failures across LLM-related nodes, including LLM and Question Classifier.
• Knowledge Retrieval node execution failures caused by incompatible enum values
• improper Weaviate client cleanup
