## Description
This PR introduces triplet embeddings via a new
create_triplet_embeddings memify pipeline.
The pipeline reads the graph in batches, extracts properties from graph
elements based on their datapoint types, and generates combined triplet
embeddings. These embeddings are stored in the vector database as a new
collection.
Changes in This PR:
-Added a new create_triplet_embeddings memify pipeline.
-Added a new get_triplet_datapoints memify task.
-Introduced a new triplet_completion search type.
-Added full test coverage
--Unit tests: memify task, pipeline, and retriever
--Integration tests: memify task, pipeline, and retriever
--End-to-end tests: updated session history tests and multi-DB search
tests; added tests for triplet_completion and memify pipeline execution
Acceptance Criteria and Testing
Scenario 1:
-Run default add, cognify pipelines
-Run create triplet embeddings memify pipeline
-Verify the vector DB contains a non empty Triplet_text collection.
-Use the new triplet_completion search type and confirm it works
correctly.
Scenario 2:
-Run the default add and cognify pipelines.
-Do not run the triplet embeddings memify pipeline.
-Attempt to use the triplet_completion search type.
-You should receive an error indicating that the triplet embeddings
memify pipeline must be executed first.
