fix(sift): change reranking from invalid 'rerank' to 'position-aware'

chooseSiftRetrievers returned reranking: 'rerank' which is not a valid
sift CLI value. Valid values are: none, position-aware, llm, jina, gemma.
This caused vector searches to fail with 'invalid value for --reranking'.

Fix: use 'position-aware' for scoped subdir searches. This is the
structural reranking that pairs with the vector retriever strategy.

Tests: 9/9 in sift-retriever-scope.test.mjs updated and passing.
Full suite: 178 files / 1845 tests pass.
