[Release] Set version to 0.57.0

[Mark Hildebrand (hildebrandmw)]

Breaking Changes

Flat search visitors are now query-aware (#1359)

• flat::FlatIndex  has been removed. The search entry point is now the free function flat::knn_search, and the DistancesUnordered visitor is constructed per-query rather than reused. The ElementRef, QueryComputer, and QueryComputerError associated types and the visitor GAT have also been removed. DistancesUnordered now yields (id, distance) pairs directly.

Migration: Callers of the old FlatIndex/visitor API should:

1. Drop FlatIndex and construct your DistancesUnordered visitor directly for the query being searched.
2. Replace calls into the removed wrapper with flat::knn_search(&mut visitor, k, processor, query, &mut output).
3. Remove any ElementRef/QueryComputer implementation, fuse scanning and distance computation directly in your DistancesUnordered::distances_unordered implementation.
