Release v2.5.3

- Fix #1: MemoryConfig Pydantic validation - add _prepare_mem0_config() to strip
  PraisonAI-specific reranker fields (enabled, default_rerank) before passing to
  mem0, which only accepts provider and config fields

- Fix #2: LLM Reranker 'Chat' object not callable - check if client.chat is
  callable, not just if it exists. OpenAI client has chat as namespace object.
  Also handle max_completion_tokens vs max_tokens for different model versions.

- Fix #3: Chroma vector store metadata validation - ensure non-empty metadata
  dicts by adding placeholder key when metadata is empty or None

- Fix test file issues: add user_id parameter (required by mem0 API), handle
  dict return type from knowledge.search, use gpt-4o-mini for reranker test
  (gpt-5-nano returns empty responses with max_completion_tokens=10)
