Enhance VectorStore filtering with debug logging and update similarity validation

This commit improves the filtering logic in the VectorStore class by adding detailed debug logging to track the metadata filtering process. It also updates the similarity validation memory JSON to change the current tier from "im" to "stm". Additionally, the SimilaritySearchTestSuite is modified to include new expected memory IDs and adjust the minimum score and result limit for specific tests, enhancing the robustness of similarity search validations.
