- Modified `getRelevantMemories` in `src/services/memory/index.js` to accept optional `ranker` and `cache` parameters for dependency injection.
- Added `test/memory-index.test.mjs` with comprehensive unit tests for `getRelevantMemories` using `node:test` mocks.
- Verified that existing behavior is preserved via default parameters.
