Purpose

Fixes #10772

Support single and batch primary-key vector queries with Ray using the Python read backend.

Search bucket splits in parallel and merge candidates on the driver, preserving global Top-K, refinement, filtering, snapshot consistency, and deletion-vector semantics.

Tests

  • 218 targeted reader, query, and Ray regression tests passed.
  • Ray execution tested with local worker processes.
  • Configured Flake8 checks and git diff --check passed.
