Forward-merge triggered by push to release/26.08 that creates a PR to keep main up-to-date. If this PR is unable to be immediately merged due to conflicts, it will remain open for the team to manually merge. See forward-merger docs for more info.

Companion PR to [cuvs!2035](NVIDIA/cuvs#2035), addresses #124.

Existing CAGRA search code path for each search query:
- Call CAGRA search API on one index segment
- Copy results back to host
- Add results into host-side global top-k priority queue
- Repeat for all index segments

Proposed change:
- Leverage new multi-segment CAGRA search API to launch all per-segment searches in one API call
- Leave results on device and run GPU-accelerated select-k API to compute global top-k
- Copy final top-k results to host
