Summary by CodeRabbit

• Chores
  • Bumped product version to 26.06.00.
  • Updated core dependencies (libraft, librmm, pylibraft, rapids-xgboost) to version 26.6 across build and runtime environments.
  • Updated build workflows to use main branch versions and upgraded container images.

Walkthrough

This PR upgrades the project version from 26.04 to 26.06 across build configurations, workflow references, and dependency specifications. Changes include updating GitHub Actions workflow references to use the main branch instead of python-3.14 tags, bumping container image versions, and synchronizing all Rapids-related package dependencies to 26.6.* across conda environments and Python projects.

Changes

Cohort / File(s)	Summary
GitHub Workflows .github/workflows/build.yaml, .github/workflows/pr.yaml, .github/workflows/test.yaml	Updated reusable workflow references from python-3.14 tag to main branch across multiple jobs (cpp-build, python-build, docs-build, wheel builds, conda operations). Updated container image references from 26.04-latest to 26.06-latest in docs-build and related jobs.
Version Identifier VERSION	Bumped version string from 26.04.00 to 26.06.00.
Conda Environment Configurations conda/environments/all_cuda-129_arch-*.yaml, conda/environments/all_cuda-131_arch-*.yaml, conda/environments/clang_tidy_cuda-*_arch-*.yaml, conda/environments/cpp_all_cuda-*_arch-*.yaml	Updated Rapids-related dependencies (libraft, librmm, libraft-headers, pylibraft, rapids-xgboost) from 26.4.\* to 26.6.\* with preserved lower bounds (>=0.0.0a0) across all CUDA 12.9 and 13.1 architecture variants.
Global Dependency Manifest dependencies.yaml	Updated 18+ dependency declarations from 26.4.\* to 26.6.\* across multiple sections (libnvforest, nvforest, libraft, librmm, pylibraft, rapids-xgboost and their CUDA-suffixed variants), maintaining existing anchor references and compatibility constraints.
Python Project Dependencies python/libnvforest/pyproject.toml, python/nvforest/pyproject.toml	Updated libraft, librmm, libnvforest, and pylibraft version specifiers from 26.4.\* to 26.6.\* in both dependency and build backend matrix entries.
