* fix(memory): add input_type to Voyage AI embeddings for improved retrieval

Voyage AI recommends passing input_type='document' when indexing and
input_type='query' when searching. This improves retrieval quality by
optimising the embedding space for each direction.

Changes:
- embedQuery now passes input_type: 'query'
- embedBatch now passes input_type: 'document'
- Batch API request_params includes input_type: 'document'
- Tests updated to verify input_type is passed correctly

* Changelog: note Voyage embeddings input_type fix (#10818) (thanks @mcinteerj)
