Consolidates current developer documentation in a versioned Sphinx Developer Guide and makes those sources canonical.

Changes

  • Moves the Python, estimator, C++/CUDA, and benchmarking guides out of wiki/.
  • Removes obsolete historical guidance and folds useful definition-of-done requirements into the relevant topical guides.
  • Modernizes the C++ guide around current RAFT, RMM, logging, testing, and multi-GPU conventions.
  • Publishes the primarily internal C++ API reference through Sphinx and Breathe with explicit stability and input-validation disclaimers.
  • Replaces the separate libcuml Doxygen site with a version-matched redirect to the integrated reference.

Supersedes #8544.

Closes #8590

@divyegala, could you please review this PR, particularly the updated C++ developer guidance and how the internal C++ API is presented? It makes the C++ API’s current stability and input-validation guarantees explicit.

  • Documentation Cleanup

    • Removed legacy wiki documentation and updated references to current Developer Guide content.

Walkthrough

The change consolidates developer documentation in Sphinx, adds C++/CUDA and C++ API sections, updates Python and benchmarking guidance, integrates Doxygen XML through Breathe, and removes legacy wiki documentation.

Changes

Developer documentation consolidation

Layer / File(s) Summary
Unified documentation build pipeline
.gitignore, build.sh, ci/build_docs.sh, cpp/Doxyfile.in, docs/source/conf.py, dependencies.yaml, conda/environments/*, docs/README.md
Doxygen now generates XML for Breathe. Sphinx now publishes combined Python and C++ documentation. The build includes a libcuml redirect and XML cleanup.
Developer Guide structure and C++ documentation
docs/source/developer_guide/*, docs/source/index.rst, wiki/*
Added Developer Guide navigation, C++/CUDA development guidance, and C++ API namespace pages. Removed legacy wiki documentation.
Python and benchmarking guide updates
docs/source/developer_guide/python/*, docs/source/developer_guide/benchmarking.md
Updated validation, testing, profiling, estimator, output-type, decorator, and benchmark guidance.
Repository guidance and documentation wiring
.coderabbit.yaml, .github/*, CONTRIBUTING.md
Updated documentation paths, ownership rules, workflow file groups, and contributor guidance to use the current Developer Guide locations.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~30 minutes

Change: Other

Suggested reviewers: jameslamb

Merge Risk: 🔵 Low · up to 9b8e4

The documentation consolidation is broadly mergeable, but contributors may miss a profiling prerequisite and C++ API reviewers are not explicitly prompted to verify input-validation documentation.

Explanation

The incremental changes include unrelated build and dependency changes. ci/build_wheel_libcuml.sh adds a libkvikio.so wheel exclusion. dependencies.yaml changes CUDA, cuda-bindings, and scikit-learn dependency behavior and versions. cpp/CMakeLists.txt adds wheel library discovery, and the RAFT/CUVS files change repository forks. These changes are not required for consolidating developer documentation in Sphinx.

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 1 functions across 3 files. (1 skipped: 1 unsupported.)
