merge release/26.06 into main

[jameslamb]

Closes #2113

Fixes forward-merge conflicts

[jameslamb]

This shows fewer commits than #2113 because #2140 was merged a few hours ago.

So it just has the 2 commits from release/26.06 that are missing on main + a merge commit fixing conflicts.

The conflict resolution was non-controversial (just re-generating the conda env files in conda/environments/). Stopping CI to save resources and admin no-squash merging this.

📝 Walkthrough

Walkthrough

This PR excludes CuPy versions 14.0.0 and 14.1.0 from all dependency constraints across the codebase. The change updates source dependency definitions, conda environment specifications for multiple CUDA versions, a conda recipe, and Python package test dependencies with consistent version exclusions while preserving the 13.6.0 minimum requirement.

Changes

CuPy version exclusion policy

Layer / File(s)	Summary
Source dependency definitions dependencies.yaml	Core dependency constraints are updated to exclude CuPy 14.0.0 and 14.1.0 for both unsuffixed and CUDA-suffixed cupy requirements and the CUDA-13 fallback alias.
Conda environment and recipe specifications conda/environments/all_cuda-129_arch-aarch64.yaml, conda/environments/all_cuda-129_arch-x86_64.yaml, conda/environments/all_cuda-132_arch-aarch64.yaml, conda/environments/all_cuda-132_arch-x86_64.yaml, conda/environments/bench_ann_cuda-129_arch-aarch64.yaml, conda/environments/bench_ann_cuda-129_arch-x86_64.yaml, conda/environments/bench_ann_cuda-132_arch-aarch64.yaml, conda/environments/bench_ann_cuda-132_arch-x86_64.yaml, conda/recipes/cuvs-bench/recipe.yaml	The version exclusions are applied consistently across all eight conda environment definitions for CUDA 12.9 and 13.2 on both architectures, plus the cuvs-bench conda recipe.
Python package test dependency constraint python/cuvs/pyproject.toml	The test extra's cupy-cuda13x dependency is updated to exclude CuPy 14.0.0 and 14.1.0 alongside the minimum version requirement.
