Vector pre-filter planning currently scans deletion vectors for the entire snapshot even though indexed vector searches only consume indexed row ranges. This can read unrelated deletion-vector files and add unnecessary planning work. Push indexed row ranges into live-row snapshot planning while preserving the existing full-text path. Add regression coverage to verify deletion vectors outside indexed ranges are not read. Signed-off-by: QuakeWang <wangfuzheng0814@foxmail.com>

Purpose
Vector live-row pre-filter planning scans deletion vectors for the entire snapshot, even though indexed vector search only consumes row ranges covered by index splits. This reads unrelated deletion-vector files and adds unnecessary planning work.
This change pushes indexed row ranges into snapshot planning so files and deletion vectors outside those ranges are pruned. The existing full-text live-row path remains unchanged.
